Conversion of standardized ReadMe file for
catalog into FORTRAN code for loading all data files into arrays.
Note that special values are assigned to unknown or unspecified
numbers (also called NULL numbers);
when necessary, the coordinate components making up the right ascension
and declination are converted into floating-point numbers
representing these angles in degrees.

*Note (1): Sexagesimal, equatorial position-based source name in the form:
* hhmmssss+ddmmsss[ABC...].
* The full naming convention for 2MASS All-Sky Release PSC sources has
* the form "2MASS Jhhmmssss+ddmmsss[ABC...]", where "2MASS" indicates
* that the source is from the All-Sky PSC, "J" indicates the position is
* J2000, and the optional trailing letters are used to distinguish
* sources with otherwise duplicate names. The "2MASS J" prefix is not
* listed explicitly in the designation column.
*Note (2): This is the selected "default" magnitude for each band, [JHK].
* If the source is not detected in the band, this is the 95% confidence
* upper limit derived from a 4" radius aperture measurement taken at the
* position of the source on the Atlas Image. The origin of the default
* magnitude is given by the first character of the Rflg value
* (Rflg). This column is null if the source is nominally detected in
* the band, but no useful brightness estimate could be made
* (Rflg="9").
*Note (3): This is the corrected photometric uncertainty [JHK]cmsig for
* the default magnitude. If Rflg="2", this is the measurement error
* from the profile-fitting procedure, corrected to be consistent with
* observed repeatability statistics. If Rflg="1" or "4", this is the
* RMS of the brightness measured in aperture photometry on the
* individual frames. If Rflg="3", the uncertainty is derived from the
* residuals to the 1-d radial profile fit to the unsaturated wings of
* the bright star.
*
* If the value is >8.0, it is a flag value indicating that a meaningful
* uncertainty could not be determined for the source. This column is
* null if the default magnitude is a 95% confidence upper limit
* (Rflg="0" or "6") or if the source is not measurable (Rflg="9").
*Note (4): Combined, or total photometric uncertainty [JHK]msigcom
* for the default magnitude in that band. The combined uncertainty is
* derived from the following relation:
*
* e_[JHK]mag = sqrt([JHK]cmsig^2^ + [JHK]_zperr_^2^
* + fferr^2^ + [r1normrms^2^])
*
* where
*
* cmsig = Corrected band photometric uncertainty
* zperr = Nightly photometric zero point uncertainty = 0.011 mag
* fferr = Flat-fielding residual error = 0.005 mags
* r1normrms = R1 normalization uncertainty = 0.012 mags
* (applied only for sources with Rflg="1")
*
* This column is null if the default magnitude is a 95% confidence upper
* limit (i.e. the source is not detected, or inconsistently deblended in
* the band).
*Note (5): Three character flag, one character per band [JHK],
* that provides a summary of the net quality of the default photometry
* in each band, as derived from the Read Flag (Rflg), measurement
* uncertainties ([jhk]cmsig), scan signal-to-noise ratios ([jhk]snr),
* frame-detection statistics (Ndet), and profile-fit reduced chi-squared
* values ([jhk]psfchi). The value for Qflg is set for a band
* according to the precedence of the table below. For example, a source
* that is tested and meets the conditions for category "X" is not tested
* for subsequent qualities.
*
* X = There is a detection at this location, but no valid brightness
* estimate can be extracted using any algorithm. Rflg="9" and
* default magnitude is null.
*
* U = Upper limit on magnitude. Source is not detected in this band
* (Rflg="0"), or it is detected, but not resolved in a consistent
* fashion with other bands (Rflg="6"). A value of Qflg="U"
* does not necessarily mean that there is no flux detected in this
* band at the location. Whether or not flux has been detected can
* be determined from the value of Rflg. When Rflg="0", no flux
* has been detected. When Rflg="6", flux has been detected at the
* location where the images were not deblended consistently in all
* three bands (JHKs).
*
* F = This category includes Rflg="1" or Rflg="3" sources where a
* reliable estimate of the photometric error, [jhk]cmsig, could
* not be determined. The uncertainties reported for these sources
* in [jhk]cmsig and e_[jhk]mag are flags and have numeric
* values >8.0.
*
* E = This category includes detections where the goodness-of-fit
* quality of the profile-fit photometry was very poor (Rflg=2 and
* [jhk]psfchi>10.0), or detections where psf fit photometry did
* not converge and an aperture magnitude is reported (Rflg=4), or
* detections where the number of frames was too small in relation
* to the number of frames in which a detection was geometrically
* possible (Rflg="1" or Rflg="2").
*
* A = Detections in any brightness regime where valid measurements
* were made (Rflg="1","2" or "3") with
* [jhk]snr>10 AND [jhk]cmsig<0.10857.
*
* B = Detections in any brightness regime where valid measurements
* were made (Rflg="1","2" or "3") with
* [jhk]snr>7 AND [jhk]cmsig<0.15510.
*
* C = Detections in any brightness regime where valid measurements
* were made (Rflg="1","2" or "3") with
* [jhk]snr>5 AND [jhk]cmsig<0.21714.
*
* D = Detections in any brightness regime where valid measurements
* were made (Rflg="1","2" or "3") with
* no [jhk]snr OR [jhk]cmsig requirement.
*Note (6): The read flag indicates the source of J,H,K "default" magnitudes
* as a 3-digit integer, where the 1st digit corresponds to the J band,
* the 2nd to the H band, and the 3rd to the Ks band. Rflg values of
* "1", "2" or "3" generally indicate the best quality detections,
* photometry and astrometry (although other quality flags must be
* considered). Values of "0", "4", "6" and "9" in a band indicate
* either non-detections, or generally poor quality photometry and
* positions. The definitions of the Rflg values are:
*
* 0 = Source is not detected in this band. The default magnitude
* is the 95% confidence upper limit derived from a 4" radius
* aperture measurement taken at the position of the source on the
* Atlas Image. The sky background is estimated in an annular region
* with inner radius of 14" and outer radius of 20".
*
* 1 = The default magnitude is derived from aperture photometry
* measurements on the 51 ms "Read_1" exposures. The aperture radius
* is 4", with the sky background measured in an annulus with an
* inner radius of 14" and an outer radius of 20". Used for sources
* that saturate one or more of the 1.3s "Read_2" exposures, but are
* not saturated on at least one of the 51 ms "Read_1" frames.
*
* 2 = The default magnitude is derived from a profile-fitting
* measurement made on the 1.3 sec "Read_2" exposures. The
* profile-fit magnitudes are normalized to curve-of-growth
* corrected aperture magnitudes. This is the most common type in
* the PSC, and is used for sources that have no saturated pixels in
* any of the 1.3 sec exposures.
*
* 3 = The default magnitude is derived from a 1-d radial profile
* fitting measurement made on the 51 ms "Read_1" exposures. Used
* for very bright sources that saturate all of the 51 ms "Read 1"
* exposures.
*
* 4 = The default magnitude is derived from curve-of-growth-corrected
* 4" radius aperture photometry measurements on the 1.3 s "Read_2"
* exposures. This is used for sources that are not saturated in any
* of the Read_2 frames, but where the profile-fitting measurements
* fail to converge to a solution. These magnitudes are the same as
* the standard aperture magnitudes (Jstdap, Hstdap, Kstdap), but
* when they are the default magnitudes, it generally implies that
* they are low quality measurements.
*
* 6 = The default magnitude is the 95% confidence upper limit derived
* from a 4" radius aperture measurement taken at the position of the
* source on the Atlas Image. The sky background is estimated in an
* annular region with inner radius of 14" and outer radius of 20".
* This is used for pairs of sources which are detected and resolved
* in another band, but are detected and not resolved in this band.
* This differs from a Rflg="0" because in this case there is a
* detection of the source in this band, but it is not consistently
* resolved across all bands.
*
* 9 = The default magnitude is the 95% confidence upper limit derived
* from a 4" radius aperture measurement taken at the position of the
* source on the Atlas Image. The sky background is estimated in an
* annular region with inner radius of 14" and outer radius of 20".
* This is used for sources that were nominally detected in this
* band, but which could not have a useful brightness measurement
* from either profile fitting or aperture photometry. This often
* occurs in highly confused regions, or very near Tile edges where
* a significant fraction of the measurement aperture of sky annulus
* falls off the focal plane.
*Note (7): Blend flag. Three character flag, one character per band [JHK],
* that indicates the number of components that were fit simultaneously
* when estimating the brightness of a source:
*
* 0 = Source is not detected, or is inconsistently deblended in that
* band.
*
* 1 = One component was fit to the source in R_2 profile-fitting
* photometry (Rflg="2"), or default magnitudes are from aperture
* photometry (Rflg="1" or "4") or saturated star 1-d radial
* profile-fitting (Rflg="3").
*
* >1 = More than one component was fit simultaneously during R2
* profile-fit photometry, where the value of the field is the
* number of components simultaneously fit. The maximum number of
* components is 7 in any band for the PSC, so this Bflg is always
* a three character flag. Multi-component fitting occurs only for
* profile-fitting, and only when more than one detection is found
* within ~5". Single detections that are not well-fit by a single
* PSF are not split.
*Note (8): Contamination and confusion flag. Three character flag, one
* character per band [JHKs], that indicates that the photometry and/or
* position measurements of a source may be contaminated or biased due to
* proximity to an image artifact or nearby source of equal or greater
* brightness. The Cflg in each band is set in hierarchical order
* according to the following table, in the event a source is affected by
* more than one artifact or condition:
*
* p = Persistence. Source may be contaminated by a latent image left
* by a nearby bright star.
*
* c = Photometric Confusion. Source photometry is biased by a nearby
* star that has contaminated the background estimation. This is
* very common in high source density regions.
*
* d = Diffraction spike confusion. Source may be contaminated by a
* diffraction spike from a nearby star.
*
* s = Electronic stripe. Source measurement may be contaminated by a
* stripe from a nearby bright star.
*
* b = Bandmerge confusion. In the process of merging detections in
* the different bands for this source, there was more than one
* possible match between the different band components. This occurs
* in regions of very high source density, or when multiple sources
* were split in one band but not another.
*
* 0 = Source is unaffected by known artifacts, or is not detected in
* the band.
*
* Non-zero values the Cflg in any band is an indicator that the
* measurements of that source may be contaminated.
*Note (9): ndet is a six-character flag, two characters per band [JJHHKsKs],
* that indicates the number frames on which a source was detected, N,
* and the number of frames on which the source could have been measured,
* M. The first digit in the pair for each band, N, gives the number of
* frames on which there were >3 sigma aperture photometry detections of
* the source. The second digit for each band, M, gives the number of
* frames on which aperture measurements were possible. Normally, M=6,
* (occasionally M=7 because the scanning step size was slightly less
* than 1/6 of the frame size). M can be <6 if frames are "lost" because:
* a) there were masked pixels within the source aperture due to cosmic
* ray detections, noisy pixels, meteor trails, etc, or b) there were
* saturated pixels within the source aperture. Values of M<6 are not
* uncommon, but do indicate an effective loss of coverage and
* sensitivity for a source.
*
* The values of N and M for a band always pertain to the aperture
* photometry on the 51 ms "Read_1" exposures if Rflg="1", and to the
* aperture photometry on the 1.3 s "Read_2" exposures if Rflg="2" or
* "4". Sources that are saturated on all of the Read_1 frames
* (Rflg="3") have N=0 because no aperture photometry was possible.
*
* Sources with signal-to-noise ratios >8-9 should be detected on all
* available frames. Values of N < M for such sources are an indication
* of possible loss of measurement integrity. Values of N < M, or even
* N=0, are normal for fainter sources because they are too faint on
* individual frames to yield a >3 sigma detection.
*Note (10): Extended source "contamination" flag. A value of
* Xflg="2" indicates that this point source falls within the elliptical
* boundary of an XSC source defined by the semi-major axis and
* ellipticity of the 20 mag.arcsec^-2^ Ks-band elliptical isophote
* (r_k20fe)+10%, for XSC sources where r_k20fe is >10''. Sources so
* indicated are often foreground stars superimposed on background
* galaxies, or sometimes extractions of pieces of the galaxy or nebula.
* The point source photometry for these sources is probably contaminated
* by the surrounding structured extended emission. Point sources can
* still be superimposed on extended sources and remain unflagged if the
* XSC source shape is not well-described by an ellipse.
*
* This flag also denotes (Xflg="1") PSC sources that are equivalent to
* sources in the XSC, but only for XSC sources with r_k20fe is >10''.
* Since most XSC sources have semi-major axes <10'', Xflg does not
* identify all PSC sources with exact XSC counterparts. Use the extKey
* to identify all PSC sources that were found to be resolved relative to
* a single point-spread function.
*
* 0 = Source does not fall within the elliptical profile of an extended
* source with semi-major axis >10'', or it is not identified
* exactly with an XSC source with semi-major axis >10''. However,
* the source may correspond exactly to a smaller XSC source.
*
* 1 = Source is resolved by 2MASS, and is equivalent to a source in the
* XSC that has a semi-major axis >10'' in size. Users must refer to
* the extKey to identify all PSC sources with XSC counterparts.
*
* 2 = Source falls within the elliptical boundary of an XSC source that
* has a semi-major axis >10'' in size.
*Note (11): Minor Planet Flag. Indicates if this source is associated
* with the predicted position of a known minor planet, comet, planet or
* planetary satellite. This association does not guarantee that the PSC
* source is a detection of the solar system object.
*
* 0 = Source is not associated with a known solar system object
*
* 1 = Source is associated with the predicted position of a known
* solar system object. The name and orbital data for the associated
* objects are given in the Known Asteroid Detection List, Known
* Comet Detection List, and Planet and Planetary Satellite
* Detection List. The associated PSC source is cross-referenced in
* those Lists via the value of ptsKey.
*Note (12): Galactic coordinate for 2MASS source derived by precessing
* reconstructed ra and dec to B1950, and performing rotational
* transformation into lII, bII coordinate system. This coordinate should
* not be used as an astrometric reference because it has been rounded to
* 0.001 deg.
*Note (13): The Julian Date of the source measurement is accurate to
* +/-30seconds. This value is extrapolated from the start time of the
* Survey scan using the difference between the declinations of the
* source and the first row in the Tile divided by the scanning rate of
* the telescope (approximately 5sec). The scanning rate of the two 2MASS
* telescopes was slightly different because of the need to optimize the
* dithering of images on the arrays.
*Note (14): Used in conjunction with the use flag, this numerical flag
* indicates whether the source falls in a Tile overlap region, and if
* so, if it was detected multiple times.
*
* 0 = The source does not fall within a Tile overlap region
* (use="1"), or it falls in an overlap region and there were no
* sources detected within 2" of its position in the overlapping
* Tile (use="0").
*
* 1 = The source falls within a Tile overlap region, and there is one
* source detected within 2" of its position in the overlapping Tile.
*
* >1 = The source falls within a Tile overlap region, and there are
* multiple sources detected within 2" of its position in the
* overlapping Tile, and/or within its own Tile. This implies
* confusion in the multiple source resolution procedure.
*Note (15): Used in conjunction with the dup flag, this numerical flag
* indicates if a source falls within a Tile overlap region, and whether
* or not it satisfies the unbiased selection rules for multiple source
* resolution.
*
* 1 = The source does not fall in a Tile overlap region
* (dup="0"), or it falls in an overlap region, but lies farther
* from its scan edge than any apparition of the source in another
* Tile. A source must have use="1" to be considered part of the
* sub-Catalog that satisfies the 2MASS Level 1 Science Requirements
*
* 0 = The source falls in a Tile overlap region, but does not have
* a detection within 2" of its position in any overlapping Tiles.
* PSC sources with use="0" will always have dup="0". Such
* objects are usually faint, and thus toggling above and below the
* detection limits, or may have moved between the scans of the
* different Tiles.
*Note (16): The catalog ID and other association parameters are given for
* the closest optical match found within 5 arcsec. The ID consists of a
* single-letter abbreviation for the catalog (e.g., 'T' for Tycho 2, 'U'
* for USNO-A2.0). '0' means no optical source was found.
*Note (17): The optical association information is unreliable for sources
* with |dec|>86{deg}, because of an error in the 2MASS/USNO-A2.0 position
* correlation procedure that caused associations to be missed in the
* vicinity of the equatorial poles. If the source has |dec|>86{deg}, a
* value of a="0" does not necessarily mean that there is not an optical
* association within 5 arcsec of the 2MASS position.
*Note (18): the standard aperture magnitude is the curve-of-growth corrected
* average brightness measured in a 4" radius aperture centered on the
* source position on each of the available 1.3 s "Read_2" frames. The
* column is empty if the source is not detected in the band (Rflg="0"),
* or if it is saturated in all of the 1.3 s "Read 2" exposures for the band.
