2020-06-30 Dan and Maciej about forced gain modes

Calibration rows

Each ASIC has (176+2 rows x 192 columns), the last two rows are the calibration rows. These rows are not connected to the sensor and are constructed without a pixel/sensor interface. They will be powered just like any other pixel in the ASIC, therefore, they see similar voltages, noise, etc just like other pixels.

...

The force switch mode should be ignored. It is a debugging mode that should not be used for calibration.
Gabriel can explain how to do the calibration if needed.
