General news:
XSHOOTER news: 2015-02-10: QC parameters on the slice counts ratio (from IFU HC flats) are a concern.
Report news: 2015-02-09 Gain thresholds have been relaxed because of new detmon with new upper threshold of 40000 ADU. As soon as the new mean value and scatter are known, thresholds will be adapted again. [whummel@eso.org]

This plot

The gain is derived from a set of paired flat fields with identical exposure time, using the Photon Transfer Curve (PTC) method. Since 2013-08-01, flats covering the full dynamic range are taken into account, also flats already in the non-linear regime, for which the PTC is not corrected for. A smaller slope in the PTC results in higher gain values. For more information see 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
