This plot

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 rms_fit (PRO.WSOL.RMS) which describes the rms of the residuals of the accepted line positions against the dispersion solution. This plot monitors the HC data taken in high resolution (H525.8B) and low resolution (L543.1, Medusa1 and 2 only).

Check the N_LINES plot of this group for the number of lines accepted for the dispersion solution, and the RESOL plot for resolution monitoring.

Check also the ARCLAMP plot under "lamp stability", to check the efficiency of the ARC lamp.  

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
