This is the trending plot for the ISAAC arc lamp calibrations of the LW-arm
The QC parameter is the dispersion as derived from the wavelength solution of the pipeline recipe (HIERARCH ESO QC DISPC02) . The parameter is given in ang/pixel units.
These plots describe:
3. Dispersion for LW-arm, LR-grating, SH-filter.
4. Dispersion for LW-arm, LR-grating, SL-filter.
6. Dispersion for LW-arm, MR-grating, J+Block-filter.
7. Dispersion for LW-arm, MR-grating, SH-filter.
8. Dispersion for LW-arm, MR-grating, SL-filter.
