  • Use universal calibration object (for all detectors!):
    PSCalib::CalibPars *calibpars = new PSCalib::CalibPars(calibDir, source, runNumber, print_bits);
    where source defines the detector type

  • Use universal (for all detectors!) modules for each calibration type:
    pdscalibdata/include/DetPedestalsV1.h          -  loads pedestals from file, returns ndarray of pedestals
    pdscalibdata/include/DetCommonModeV1.h  -  the same for common mode
    pdscalibdata/include/DetPixelGainV1.h            - the same for pixel gain
    pdscalibdata/include/DetPixelStatusV1.h         - the same for pixel status

  • Use universally (for all detectors!) pre-defined types of parameters :
    pdscalibdata::DetPedestalsV1::pars_t   = float
    pdscalibdata::DetCommonModeV1::pars_t  = uint16_t 
    pdscalibdata::DetPixelStatusV1::pars_t = uint16_t
    pdscalibdata::DetPixelGainV1::pars_t   = float
  • Define the groupName="PNCCD::CalibV1" from dictionary for source="Camp.0:pnCCD.1" - this means that we will never change the groupName !

  • Save/retrieve ndarray type/shape from file header, for example:

    Code Block
    # RULES:
# Lines starting with # in the beginning of the file are considered as comments or pseudo-comments for metadata
# Lines without # with space-separated values are used for input of parameters
# Empty lines are ignored

# Optional fields:
# TITLE:      This is a file with pedestals
# DATE_TIME:  2014-01-30 10:21:23
# AUTHOR:     someone
# EXPERIMENT: amotut13
# DETECTOR:   Camp.0:pnCCD.1
# CALIB_TYPE: pedestals

# Mandatory fields to define the ndarray<TYPE,NDIMS> and its shape as unsigned shape[NDIMS] = {DIM1,DIM2,DIM3}
# TYPE:       float
# NDIMS:      3
# DIM1:       4
# DIM2:       255
# DIM3:       255
