This is the Health Check plot for the quality of the dispersion solution in the GIRAFFE arclamp calibration data. We display here the QC1 parameter nlin_acc which describes the average number of lines per fibre accepted for the dispersion solution. This plot monitors the HC data taken in high resolution (H525.8B) and low resolution (L543.1, Medusa1 and 2 only).
The ops log data contain only the parameter PRO.WSOL.NLINES which measures the nominal number of lines per fibre, before acceptance. This value is usually slightly higher than nlin_acc.
The purpose of this plot is to monitor the ability of the pipeline to derive a reasonable wavelength solution. Plots 1-5 show the HC settings for high resolution. Plots 6-7 show the HC settings for the low resolution grating. Plots 8-10 show all settings per wavelength: Medusa1/2 high-resolution (8), IFU1/2/Argus high-resolution (9), and Medusa1/2 low resolution (10).
Check the RMS plot of this group for the typical rms of the
dispersion solution, and the RESOL plot for monitoring the resolution.
