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

Trending plot for drift measurements.

These are wavelength calibrations that are measured typically during the afternoon with ThAr in one fibre and Fabry-Perot (FP) in the other fibre. The FP lines are compared to a reference (typically from the morning calibrations) and a shift in pixels is determined. This shift is converted into a radial velocity precision, 0.002 pixels correspond to 1 m/s, and devided by the time difference to the reference.

Plots 1, 2, 5, and 6 show the shift in pixels; plots 3, 4, 7, and 8 the converted values in cm/s/h. Only measurements where the time difference to the FP reference is at least one hour are plotted.

Downloaded values are always in pixels, the conversion to cm/s/h is done internally. Also all measurements are available including values where the time difference is less than one hour. This can be checked with the delta_time_fp column that has the time difference in fractions of day.  


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
