This plot
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.

here.
General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
