The catalog contains 177,860 stars, 61,242 which are in either an IRAS catalog and/or the Catalog of Infrared Observations. The catalog was constructed from a number of visible astrometric catalogs, and contains position information accurate to the sub-arcsecond level. The FK5 (1988 Fricke Schwan and Lederle), FK5 Extension (1991 Fricke, Schwan and Corbin), Astrographic Catalog of Reference Stars (1991 Corbin and Urban), Position and Proper Motion Catalog (1988 Roeser and Bastian) and PPM South (1991 Bastian et al.) were the sources of position and magnitude information. The PPM and FK5 catalogs contain 1-D spectral type information, and this was supplemented where possible with 2-D MK spectral types. The ACRS and PPM quote photographic magnitudes. These were transformed to V magnitude using the spectral type and expected B-V color. The catalog lists astrometric source catalog identification, IR name, equatorial position at J2000 and proper motions with errors, spectral type, IRAS or CIO flux in 12, 25, 60, 100 micron bands, and estimates of flux in the MSX SPIRIT III instrument IR bands.

Spatial coincidence and color-matching criteria (based on V-[12] color and spectral type) were used to identify IR counterparts of the astrometric stars. The IRAS Point Source, Faint Source, Faint Source Reject file, and Serendipitous Survey catalogs were used to supply IR observations, as was the Catalog of Infrared Observations (1993 Gezari et al.). The IR flux in each SPIRIT III band was estimated using the V magnitude, spectral type, and IR flux (if available) to determine a blackbody spectrum for the star, which was then convolved with the system spectral response of each SPIRIT III radiometer band. Stars which were brighter than 8th magnitude in band A were retained in the final MSX IR astrometric catalog. The original version of the catalog, MSX4_2_1 quotes SPIRIT III source flux density (Jansky's) at the effective wavelength of each band. In the secondary version of the catalog, MSX4_2_1A, the in-band irradiance of each source in each band is quoted, in units of Watts per square centimeter. Both cat_j.dat and cat_i.dat are ASCII files, written in identical formats. Only the units of the SPIRIT III band flux estimates are different, as noted above. The following tables list the format of each catalog file. J_AJ_112_2862.xml
