Detailed Description

The payload class for PXD gain corrections.

The payload class stores the gain correction values for PXD sensors on a grid nBinsU x nBinsV. The values are stored as dimensionless corrections factors. The default value is 1.0.

The baseline electron to ADU conversion is given as

1) baseline_eToADU = baseline_ADCUnit / baseline_Gq

and depends on the unit of the ADC channel and the Gq of the DEPFET transistor. These basline numbers are what is applied in the PXDDigitizer.

The gain corrected conversion factor is

2) corrected_eToADU = baseline_eToADU / gain_correction

Variations inside a 2D bin will be averaged over. The Granularity of the grid can be adjusted by the user.
