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

The spectrophotometric standard star observations are taken within three days of the corresponding science observations and are meant to provide a response curve for data reduction. They can also be used to determine the efficiency of the spectroscopic modes of FORS2, provided they have been taken under photometric conditions which however is not guaranteed.

Plotted here are:
a) values for the relative efficiency of the system 'telescope + spectroscopic arm of FORS2' (top), at a representative wavelength (indicated in the comment); these values can be used for trending
b) all values for the grism and the order separation filter of the upper plot, displayed over wavelength to obtain a chromatic overview (bottom); the date range is the same as for the upper plot.

Only data points for the upper CCD are plotted. The lower CCD usually has no standard stars and no response curve.

The best current estimate of the efficiency of the spectroscopic modes of FORS2 is the upper envelope of the data points in the upper panel. Under 'data downloads' you find further information regarding the photometric stability of the night ('S' if stable, 'N' if unstable, 'U' if unknown).

More information can be found on the plot tutorial page  

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
