  recno  Record number assigned by the VizieR team. Should Not be used for identification. (meta.record)
  SDSS (char) SDSS-DR14 designation SDSS J (HHMMSS.ss+DDMMSS.s) (Name) (Note G1)   (meta.id;meta.main)
  ObsID (char) Objet identifier (ObsID) (meta.id;obs)
  Obs s Observation start date (MJD) (time.start;obs)
  Inst (char) The instrument used for the observation, ACIS for Chandra and pn/MOS1/MOS2 for XMM-Newton observations (Inst) (Note G2)   (instr.setup)
  logfdet [mW/m2] Logarithm of the detection flux limit in the 0.5-7 keV band at the position of the quasar on the detector expressed in erg/cm2/s (logfdet) (Note G3)   (phot.flux;em.X-ray)
  CTnet ct The net source counts (Note G4)   (phot.count;em.X-ray)
  S/N  Signal to noise ratio, S/N = net/sqrt(s+b/k2) (SNR) (stat.snr)
  logfx [mW/m2] Logarithm of the energy flux in the 0.5-7 keV band if the the quasar is detected expressed in erg/cm2/s (logfx) (Note G5)   (phot.flux;em.X-ray)
  f_logfx   [0 1] Detection flag in the X-ray observation, takes 1 if it's the case 0 otherwise (xdet) (meta.code)
  gamma  (n) The power-law photon index derived from our spectral fitting, it is not estimated for non-detection cases(gamma) (spect.index)
  e_gamma  (n) Lower error on gamma (gammaLo) (stat.error)
  E_gamma  (n) Upper error on gamma (gammaHi) (stat.error;stat.max)
