Query by Constraints constraints help applied on Columns (Output Order: + - )
ShowSortColumn  Constraint Explain   (UCD)
  recno  Record number assigned by the VizieR team. Should Not be used for identification. (meta.record)
  n_HIP (char) Star from the training set, or star newly classified (meta.id)
  HIP  HIP number (meta.id)
  Type (char) Type of variable (meta.code;src.var)
  PType (char) Predicted type (only in table4) (meta.code;src.var)
  logP [d] Period extracted with the Lomb-Scargle method [Log(Period)] (time.period)
  logA [---] Amplitude of the light-curve model [Log(Amplitude)] (src.var.amplitude)
  V-I mag Mean V-I colour index [V-I] (phot.color;em.opt.V;em.opt.I)
  Mhip mag Hipparcos absolute magnitude derived from the parallaxes neglecting interstellar absorption [MHipparcos] (Note 1)   (phys.magAbs)
  res/raw  Median absolute of the residuals (obtained by subtracting model values from the raw light curve) divided by the Median Absolute Deviation (MAD) of the raw light-curve values around the median [Scatter:res/raw] (stat.fit.residual)
  Skew  Unbiased weighted skewness of the magnitude distribution [Skewness] (stat.fit.param)

  log(1+A2/A1) [-] Amplitude ratio between the second harmonic and the fundamental (plus one, to avoid negative values) [Log(1+A2/A1)] (src.var.amplitude;arith.ratio)
  P2p/2P  Sum of the squares of the magnitude differences between pairs of successive data points in the light curve folded around twice the period divided by the same quantity derived from the raw light curve [P2p scatter:2P/raw] (stat.fit.param)
