ImgCalib gets the raw image from data and process it as follows:

1. subtracts pedestals,
2. subtracts

...

1. normalized background,
2. applys

...

1. gain factors,
2. applys mask, and
3. applys threshold,
   and saves the corrected image in the event.

Functionality:

• ImgCalib uses the source and key_in parameters to get the input raw image (as ndarray<double,2> object),
• gets the calibration parameters from files fname_peds, fname_bkgd, fname_gain, and fname_mask, if their names are specified,
• the specified by the file name corrections are applied per-pixel to raw data image as follows:

  Code Block
  A_cor = A_raw (1) - pedestal | if the file name is specified in {{fname_peds}} (2) - N*background | if the file name is specified in {{fname_bkgd}} (3) * gain | if the file name is specified in {{fname_gain}} (4) apply mask | if the file name is specified in {{fname_mask}} (5) apply threshold | if the threshold value is specified in {{threshold}}

• corrected image is saved in the event with key key_out.
