This plot

This is the trending report for UVES QC parameters derived from Parasitic Light frames.
These frames are taken approximately once per month, as a single exposure of 3600 secs in a dark enclosure BUT with the CCD shutter OPEN (as compared to the DARK frames where the CCD shutter is closed). These data are de-biased and combined into a MASTER_DARK, in which the average dark level is measured (in ADU/px/hr). [There are also shorter exposures, they are subject to false results. If you find an outlier, check first the exposure time under 'Data downloads'!]

The purpose of these exposures is to detect low-level contaminating light sources (e.g. LEDs) originating INSIDE the instrument.

These plots describe:

  • the DARK current in master PARASITIC_DARK (or PDARK) frames of the BLUE|REDL|REDU chips in the 1x1 binning, 225kHz, low gain readout mode
  • same for the BLUE|REDL|REDU chips in the 2x2 binning, 50kHz, high gain readout mode.
 
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
