This is the FULL 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).
Corresponding data from the GIRAFFE master calibration (re)processing project are available for the Medusa plots and marked separately.
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.
