Abstract:
   The first supplement (MDSPS1) to the Catalog of Metal-Deficient F-M Stars
   Classified Spectroscopically (MDSP) includes 289 stars selected from the
   literature sources published in 1997-1982.

Introduction:
   Recorded information includes MDSPS1 number, star numbers in 2 catalogs
   with notes on duplicity, V magnitude, (B-V)0 color, Mv, B-V color excess
   and [Fe/H], notes on colors and metallicity, stellar group, spectral type
   with reference, coded catalog number, original equinox and format codes
   for the equatorial coordinates, RA and Dec (1950.0) in radians, RA and Dec
   (1900.0, 1875.0, 1855.0), HD, BD/CD, G, LTT, and up to 13 other catalog
   designations in a numeric code.

Note on n_Vmag: values are:
    1 = Photovisual magnitude
    2 = Photographic magnitude
    3 = Red magnitude
    4 = noticeable uncertainty (marked by a colon : in the printed catalogue)
Note on n_(B-V)0: values are:
    1 = value transformed from photometry in Vilnius, Geneva, uvby
        and DDO systems
    2 = noticeable uncertainty
Note on n_VMag, n_E(B-V): values marked with:
    1 = noticeable uncertainty (marked by a colon : in the printed catalogue)
Note on n_[Fe/H]: values marked with:
    1 = noticeable uncertainty (marked by a colon : in the printed catalogue)
    2 = large uncertainty (marked by two colons  :: in the printed catalogue)
Note on n_RAs: values marked with
    1 = position listed to 0.1min and 1arcmin accuracy.
Note on Group: the group dependence was defined on the basis of all
    available information concerning the star: photometric and
    spectroscopic classification, kinematic properties, etc, see
    description in Bartkevicius, Vilnius Obs. 1983VilOB..64...24B and
    1984VilOB..66....3B; some new abbreviations have been applied:
    "MD-I" denote metal-deficient supergiants, and "MDD" denote
    dwarfs with moderate metal deficiency ([Fe/H]>-0.6).
Note on Spectrum:
    The photometric spectral type is marked by a symbol "PH" (an asterisk
    refers to a type determined in this paper). It the spectral type is
    obtained from both spectroscopic and photometric classifications, the
    symbol "SP,PH" is used. For stars with [Fe/H] values obtained from
    high-dispersion spectra, the symbol "MD" is used and the [Fe/H] value
    is given in parentheses behind. For some stars the spectral type from
    HD, SAO, AGK2, BS, and other catalogues are presented without any
    references.
Note on n_Eq: the Original Equinox is coded as:
    0 = 1950.0 1 = 1855.0 2 = 1875.0 3 = 1900.0
    4 = 1925.0 5 = 1975.0 6 = 2000.0
Note (1):
    See the file "numsys.dat" for keys to the coded identifications,
    and file "srccats.txt" for the acronyms used for catalogues.

History:
  * 11-Dec-2000: Only one equatorial position (for Equinox B1950.0) was
    kept in file data.dat -- the original file contained in addition the
    equatorial positions for equinoxes 1900, 1875 and 1875, plus the 1950
    RA and Dec in radians.
