Description:
The SKYMAP Star Catalog System consists of a Master Catalog stellar
database and a collection of utility software designed to create and
maintain the database and to generate derivative mission star catalogs
(run catalogs). It contains an extensive compilation of information on
almost 300000 stars brighter than 8.0 mag.
The original SKYMAP Master Catalog was generated in the early 1970's.
Incremental updates and corrections were made over the following years
but the first complete revision of the source data occurred with
Version 4.0. This revision also produced a unique, consolidated source
of astrometric information which can be used by the astronomical
community. The derived quantities were removed and wideband and
photometric data in the R (red) and I (infrared) systems were added.
Version 3 of the SKY2000 Master Catalog was completed in May of 2000
and represents an incremental but substantial improvement over Version
2 (Cat. V/102). A global replacement of photovisual (ptv) and
photographic (ptg) magnitudes and of Henry Draper spectral types was
performed using as sources the SAO Catalog, the PPM catalogs, and the
HD catalogs. Several hundred entries previously lacking them now have
CCD ST magnitudes from the star tracker onboard the SWAS spacecraft
(transformed to the photometric system defined by the RXTE CCD ST data
in SKY2000 Version 2). Several thousand missing HD catalog identifiers
(mostly for HD Extension stars) were added, and several hundred
missing variable star identifiers were added. 61 stars bright enough
for inclusion in SKY2000 were added, bringing the total number of
entries in the SKY2000 Version 3 Master Catalog to 299,160 (299,161
in Rev. 1).

Note on SKY2000:
Field added to SKY2000 Version 1 for SKY2000 Version 2.
Note that there are 91 stars for which the SKY2000 name (based on the
J2000 position) differs from their actual position, due to corrections
performed on some positions; the SKY2000 names were intentionally kept
identical to the original SKY2000 version. The list of these 91 stars
can be found in the "List of stars with differences" section below.
Note on m_HD:
1. indicates this the brighter component of a system with a companion
≥ 0.3 mag.
2. indicates this is the fainter component of a system with a companion
≤ 0.3 mag.
3. for a third component
9 indicates that this is a blend of two HD stars. The HD number is the
lower of the two.
Note on GCI_X:
cos(Dec)*cos(RA)
Note on GCI_Y:
cos(Dec)*sin(RA)
Note on GCI_Z:
sin(Dec)
Note on Sp:
i.e. HD, AGK3, or SAO
Note on orbPer, magMax and magMin:
Data for these fields have not been added to the SKY2000 Master Star
Catalog.
Note on n_mag1:
Photometry is on the RI system. This byte indicates whether it is
Johnson or Russian)
Note on p_mag1:
Filter used (currently, only R)
Note on n_mag2:
Photometry is on the Johnson, Eggen, or Cousins system. This byte
indicates which.
Note on p_mag2:
Filter used (currently, only I)
Note on mag3, v-mag3, e_mag3, n_mag3, p_mag3, r_mag3 and f_mag3:
Fields added to SKY2000 Version 1 for SKY2000 Version 2.
The column p_mag3 contains X, which refers to the star trackers
aboard the RXTE satellite. The response curve of these trackers
covers the 0.4 to 1.1um range, with its peak sensitivity covering
the R and I bands (.65 to .9um)
