  • ImgCalib uses the source and key_in parameters to get the input raw image (as ndarray<const T,2> object), where T stands for uint16_t, int, float, uint8_t, or double,
  • gets the calibration parameters from files fname_peds, fname_bkgd, fname_gain, fname_mask, and fname_nrmsrms, if their names are specified,

  • the specified by the file name corrections are applied per-pixel to raw data image as follows:

    Code Block
    bgColor#F7F7ED
    A_cor = A_raw
        (1) - pedestal              | if the file name is specified in the parameter "fname_peds"
        (2) - N*background          | if the file name is specified in the parameter "fname_bkgd"
        (3) * gain                  | if the file name is specified in the parameter "fname_gain"
        (4) apply mask              | if the file name is specified in the parameter "fname_mask"
        (5) apply N*RMS threshold   | if the file name is specified in the parameter "fname_nrms"
        (6) apply threshold         | if the "do_threshold" = true
  • corrected image is saved in the event with key key_out as double type.
