This plot

This is the trending plot for the ISAAC arc lamp calibrations of the SW-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:
1. Dispersion for SW-arm, LR-grating, SZ-filter. Only Argon lamp used.Bb> 2. Dispersion for SW-arm, LR-grating, J-filter. Argon (red diamont) and Xenon (blue cross).
3. Dispersion for SW-arm, LR-grating, SH-filter. Argon (red diamont) and Xenon (blue cross).
4. Dispersion for SW-arm, LR-grating, SK-filter. Argon (red diamont) and Xenon (blue cross).

5. Dispersion for SW-arm, MR-grating, SZ-filter. Both Argon and Xenon lamps are on.
6. Dispersion for SW-arm, MR-grating, J-filter. Both Argon and Xenon lamps are on.
7. Dispersion for SW-arm, MR-grating, SH-filter. Both Argon and Xenon lamps are on.
8. Dispersion for SW-arm, MR-grating, SK-filter. Both Argon and Xenon lamps are on.

The color coding is: red for Argon alone lamp exposure, blue for Xenon alone lamp exposure and black for Argon+Xenon lamp exposure. For the LR grating there is for each lamp one dedicated exposure. For the MR grating there is one exposure showing the mixed spectrum of both lamps.

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
