_DEJ2000  "d:m:s" Declination (FK5, Equinox=J2000.0) (computed by VizieR, not part of the original data. The format may include more digits than the original data because of internal accuracy requirements in VizieR and across other CDS services) (pos.eq.dec)
_RAB1950  "h:m:s" Right ascension (FK4, Equinox=B1950.0) (computed by VizieR, not part of the original data. The format may include more digits than the original data because of internal accuracy requirements in VizieR and across other CDS services) (pos.eq.ra)
_DEB1950  "d:m:s" Declination (FK4, Equinox=B1950.0) (computed by VizieR, not part of the original data. The format may include more digits than the original data because of internal accuracy requirements in VizieR and across other CDS services) (pos.eq.dec)
_Glon  deg Galactic longitude (computed by VizieR, not part of the original data. The format may include more digits than the original data because of internal accuracy requirements in VizieR and across other CDS services) (pos.galactic.lon)
_Glat  deg Galactic latitude (computed by VizieR, not part of the original data. The format may include more digits than the original data because of internal accuracy requirements in VizieR and across other CDS services) (pos.galactic.lat)
