QC1 parameters

• average temperature of camera [C] (QC1 database table uves_fmtchk, column ins_temp1_mean, product keyword INS.TEMPi.MEAN)
  Description: Mean Temperature during the exposure.
• difference of X positions to physical model (QC1 database table uves_fmtchk, column mean_dx, product keyword QC.MODEL.DIFFXAVG)
  Description: The physical model used in Formatcheck step allows to measure the difference between model predicted and detected line positions. This is useful to verify precision of physical model prediction and instrument spectral format stability.
• difference of Y positions to physical model (QC1 database table uves_fmtchk, column mean_dy, product keyword QC.MODEL.DIFFYAVG)
  Description: The physical model used in Formatcheck step allows to measure the difference between model predicted and detected line positions. This is useful to verify precision of physical model prediction and instrument spectral format stability.
• number of lines selected (QC1 database table uves_fmtchk, column nlin_sel, product keyword QC.MODEL.NLINSEL)
  Description: The physical model used in the Formatcheck step allows to predict line positions on the formatcheck frame. The selected number of lines is the subset of the total number of lines which fall in the physical model plot limits.

QC1 parameters

• median of difference in X to reference frame (QC1 database table uves_fmtchk, column median_shftx, product keyword QC.SHFTXMED)
  Description: mmeasured median shift in x from stability check
• median of difference in Y to reference frame (QC1 database table uves_fmtchk, column median_shfty, product keyword QC.SHFTYMED)
  Description: measured median shift in y from stability check
