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 wavelength day calibration consists in using the MIDI heated blackscreen and taking 3 exposures through different narrow-band filters [NeII], [SIV] and [ArIII] (having central wavelengths accurately measured in the laboratory by the manufacturer). An extra exposure is taken through a polycarbonic foil that has several absorption lines in its N-band spectrum. Exposures without filters and with closed shutter are also taken to process the exposures with filters. From the spectra obtained through the filters a fit of the lambda(X) function is performed. The procedure is performed for each setup (PRISM or GRISM, and SCI_PHOT or HIGH_SENS). The MIDI HIGH_SENS mode uses 2 windows on the detector (R1 and R2). The MIDI SCI_PHOT mode uses 4 windows (R1 to R4) We monitor here the stability of the dispersion by plotting the wavelength of a spectral channel given by the lambda(X) function computed by the reduction of the calibration data. The selected spectral channels corresponds to the expected central wavelength of the three narrow-band filters.  


General information

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

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.

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
