This catalog is a list of 1,989 sources detected along the galactic plane
between longitudes 349 and 45 degrees.  The total scanned area was 12 square
degrees and all sources brighter than magnitude 6.5 in the K band are listed.
The observations were made during 1978 and 1979 using a specially designed
multicolor photometer.  A total of 17 areas was sampled.

The data were supplied to the Astronomical Data Center, NASA Goddard Space
Flight Center, as a series of 17 files on magnetic tape, by Dr. K. Kawara.
The 17 files, representing the individual areas scanned, were moved to disk
storage, concatenated to a single file, and reformatted to minimize storage.
The sources were then sorted by increasing galactic longitude.

The format of the data is given in the following table.  The logical record
length is 62 bytes.

      ========================================================

The I, H, K, and L magnitudes are defined as fluxes for a zero-magnitude star
(um = micrometers):

   I (0.82 um) - 1.08 x 10**-12 W/cm**2/um
   H (1.61 um) - 1.20 x 10**-12 W/cm**2/um
   K (2.21 um) - 3.8  x 10**-12 W/cm**2/um
   L (3.58 um) - 6.8  x 10**-12 W/cm**2/um

The H-K colors are given only for sources of H magnitude 6.5 and brighter.
