This is the trending report for UVES QC parameters derived from DARK frames.
These frames are taken approximately once per month, as a set of 3
consecutive exposures of 3600 secs each. These data are de-biased and
combined into a MASTER_DARK, in which the average dark level is
measured (in ADU/px/hr).
These plots describe:
- the DARK current in master DARK frames of the BLUE chip in the 1x1 binning, 225kHz, low gain readout mode
- same for REDL chip, 1x1
- same for REDU chip, 1x1
- the DARK current in master DARK frames of the BLUE chip in the 2x2 binning, 50kHz, high gain readout mode
- same for REDL chip, 2x2
- same for REDU chip, 2x2
Find more information about UVES DARK frames here.
Basic QC parameters related to detector properties (like median level,
ReadOut Noise, etc ) are trended
here.
General information
Click on any of the plots to see a close-up version.
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
