This is the trending report for the QC parameters derived from UVES BIAS frames.
These plots describe:
- the read noise (RON) of the BLUE, RED LOWER and RED UPPER CCD master frame in the 1x1 binning, 225kHz, low gain readout mode;
- the same for the 2x2 binning, 50kHz, high gain readout mode
The thresholds are set as -+5% of nominal values.
These nominal values are (in ADU)
- BLUE 1x1 1.11
- REDL 1x1 1.57
- REDU 1x1 1.47
- BLUE 2x2 2.21
- REDL 2x2 2.93
- REDU 2x2 2.63
The e- to ADU conversion used are
- BLUE 1x1 1.84 ADU
- REDL 1x1 1.59 ADU
- REDU 1x1 1.46 ADU
- BLUE 2x2 0.54 ADU
- REDL 2x2 0.52 ADU
- REDU 2x2 0.52 ADU

Other QC parameters related to detector properties (like linearity, gain) 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.
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
