Simple ConstraintList Of Constraints
 
Query by Constraints constraints help applied on Columns (Output Order: + - )
ShowSortColumn  Constraint Explain   (UCD)
  recno  Record number within the original table (starting from 1) (meta.record)
  Name (char) variable star name. (meta.id;meta.main)
  RA1950 "h:m:s" Right Ascension 1950 (pos.eq.ra;meta.main)
  DE1950 "d:m:s" Declination 1950 (pos.eq.dec;meta.main)
  e_RA1950 s (n) formal (internal) mean error of the measurements at the plate location of the variable star as derived from the least squares solution to the position of the standard stars in right ascension (multiplied by cos(delta)) in seconds of time. (Note 1)   (stat.error;pos.eq.ra)
  e_DE1950 arcsec (n) formal (internal) mean error in declination in seconds of arc. (Note 1)   (stat.error;pos.eq.dec)
  Epoch yr epoch of the coordinates. (Note 2)   (time.epoch)
  Source (char) the type of the plate on which the positions were measured, or source of the measurements: L = Lopez (1985, IBVS 2837) W = Williams (1983, ApJS 53, 523) K = Kiplinger (1985, IBVS 2488) Other abbreviations are self-explanatory. (meta.note;src.morph.type;instr.plate)
  RefCat (char) Source catalogue for the reference stars. In most cases the AGK3 or the PPM catalogue could be used. However, for some fields we had to use the SAO catalogue which has a somewhat inferior accuracy. (meta.ref;pos.frame)
  Nref  (n) Number of reference stars for the coordinate determination (only for our own measurements) (meta.id)
  Rem (char) a code for remarks (Note 3)   (meta.note)
  Simbad  ask the Simbad data-base about this object (meta.ref)
  _RA.icrs "h:m:s" (n)Right ascension (ICRS) (computed by VizieR, not part of the original data) (pos.eq.ra)
  _DE.icrs "d:m:s" (n)Declination (ICRS) (computed by VizieR, not part of the original data) (pos.eq.dec)
