KPI plot for read-out noise (RON) as determined from bias calibrations.

The ESPRESSO detector can be operated with slow or fast read-out. It consists of two chips, one for the BLUE and one for the RED arm. Each chip has 16 read-out ports. QC parameters are determined per read-out port which leads to 16 different values for each QC parameter per chip.

The KPI plots are devided into fast and slow read-out. For each read-out mode, there are two plots for the red and two for the blue chip, each plot showing the values for eight read-out ports. The labels come in the form <DET>_<X>_<Y> with <DET> being the chip (BLUE or RED), <X> the x positions of the read-out on the chip (0, 1, to 7), and <Y> the y position (0 or 1).

The KPI reference values are as given in the User Manual v1.3.
