QC1 parameters

  • Mean pixel value in master BIAS [ADU] (QC1 database table uves_ccdtest, column bias_avg, product keyword PRO.DATAAVG)
    Description: Mean of the pixel values in the frame. All pixels are taken into account.
  • RMS of pixel values in master BIAS [ADU] (QC1 database table uves_ccdtest, column bias_rms, product keyword PRO.DATARMS)
    Description: Population standard deviation (sigma) of the pixel values in the frame. All pixels are taken into account.
  • average measured RON (QC1 database table uves_ccdtest, column ron_avg, product keyword QC.OUTi.RONAVG)
    Description: measured average readout noise
  • rms of measured RON (QC1 database table uves_ccdtest, column ron_rms, product keyword QC.OUTi.RONRMS)
    Description: measured error for readout noise # # CCDTEST: Flat #

QC1 parameters

  • average measured conversion factor in ADU (QC1 database table uves_ccdtest, column conad_avg, product keyword QC.OUTi.CONADAVG)
    Description: measured average conversion factor
  • rms of measured conversion factor in ADU (QC1 database table uves_ccdtest, column conad_rms, product keyword QC.OUTi.CONADRMS)
    Description: measured error for conversion factor
  • shutter error (QC1 database table uves_ccdtest, column shutter_error, product keyword QC.SHUTERR)
    Description: measured shutter error
  • positive linearity deviation % (QC1 database table uves_ccdtest, column linearity_error_p, product keyword QC.LINERRP)
    Description: positive (+) linearity deviation P stands for plus and M for minus. The numbers give the separately the positive (P) and negative (M) deviation from the linear regression curve. The regression curve should be perfectly straight, i.e., the countrates a linear function of the exposure times. The deviations give you a measure for the non-linearity.
  • negative linearity deviation % (QC1 database table uves_ccdtest, column linearity_error_m, product keyword QC.LINERRM)
    Description: positive (m) linearity deviation P stands for plus and M for minus. The numbers give the separately the positive (P) and negative (M) deviation from the linear regression curve. The regression curve should be perfectly straight, i.e., the countrates a linear function of the exposure times. The deviations give you a measure for the non-linearity.
