Instantiate object with calibration parameters

Define path to the directory with calibration types and instantiate the calib object
for run:int number with access to the calibration constants from the list 'center', 'tilt', 'pedestals':

    # Official path:
    path = '/reg/d/psdm/mec/mec73313/calib/CsPad2x2::CalibV1/MecTargetChamber.0:Cspad2x2.1/
    # or local:
    # path = '/reg/neh/home1/dubrovin/LCLS/CSPad2x2Alignment/calib-cspad2x2-01-2013-02-13/'

    calib = calpars.CSPAD2x2CalibPars(path, run, ['center', 'tilt', 'pedestals'])

Get pixel coordinates

Instantiate the coord object, using calibration parameters loaded ib the calib object and get the X and Y pixel coordinate arrays of shape (185, 388, 2):

    coord = pixcoor.CSPAD2x2PixCoords(calib)
    X,Y = coord.get_cspad2x2_pix_coordinate_arrays_pix()

Get array of calibration parameters

Get array of calibration parameters of specific type:

    peds_arr = calib.getCalibPars('pedestals')
