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 2D product spectrum of nightly acquired telluric standard stars is analyzed. The PSF of the central positive signal (ignoring both neigboring negative signals originating from the NIR double subtraction data reduction method for nodding observation) is fit with a Moffat function for each wavelength bin. The spectral trace is fit by a quadratic function:

trace = ADC_y0 + ADC_y1 * (lam - lamC) + ADC_y2 * (lam - lamC)^2.

The mean position of the spectral trace (ADC_y0) and the spectral slope (ADC_y1) as a measure of the residual optical distortion are monitored, ADC_y1 is scored in addition. ADC_y2 is available in the QC1 DB.  
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
