ShowSortColumn  Constraint Explain   (UCD)
  recno  Record number assigned by the VizieR team. Should Not be used for identification. (meta.record)
  Nmemb  The number of members belonging to the large quasar group (m) (meta.number)
  RAJ2000 deg (i) Mean right ascension of the member quasars (J2000) ({alpha}{bar}) (pos.eq.ra;meta.main)

  z  Mean redshift of the member quasars (z{bar}) (src.redshift)
  w71  The normalized goodness-of-fit weight w is scaled by w71 = w * 71 for clarity, and to distinguish those LQGs weighted higher (w71 > 1) or lower (w71 < 1) than the mean w{bar} (w71) (stat.fit.goodness;stat.weight)
