This is the trending report for the QC parameters derived from UVES BIAS frames.

These plots describe:

• the collapsed structure in Y direction 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

Outliers in the HC plot "Struct_Y", #6 ("REDU 2x2 high") are due to remnants left by previous arc observations. Arcs taken in 760-860nm settings are known to leave this kind of remnances.

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