V/109 SKY2000 Catalog, Version 4 (Myers+ 2002) ================================================================================ SKY2000 Master Catalog, Version 4 Myers J.R., Sande C.B., Miller A.C., Warren Jr. W.H., Tracewell D.A. ================================================================================ ADC_Keywords: Positional data; Cross identifications; Combined data; Surveys; 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 4 of the SKY2000 Master Catalog was completed in April 2002; it marks the global replacement of the variability identifier and variability data fields. More details can be found in the description file sky2kv4.pdf. This version supersedes the previous versions 1(V/95), 2(V/102), and 3(V/105).

Note that there are 92 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 92 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) Note on r_RV, r_Umag, r_Vmag, r_mag1, r_mag2, r_mag3: The references are normally found in the file "refs.dat"; a few references are however not explicited: 71, 82, 85, 86. -------------------------------------------------------------------------------- List
