General news: NOTE: The Health Check and calChecker services are moved to qcFlow on an instrument by instrument basis. The current pages will not be updated any longer once the move has been finished.
The links to KMOS, UVES, and ESPRESSO have been moved to a new section (qcFlow operational) at the lower part of the navigation bar.

This plot

Residuals of the fit between metrology, phase observed on the science camera, and phase observed on the fringe tracker: a * SC + b * FT + c = MET. The sum of these three OPDs should be constant. If it is not the case, the fit will show high residuals. It means that one of the three OPD quantities is not well measured: either not enough flux, bad alignment of the spectra, or unreliable metrology. The P2VM should then not be used for calibration. Repeated occurrences indicate an issue with the instrument.  


General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • 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
