Interface

Code Block

import CSPAD2x2PixCoords as pixcoor
import CSPAD2x2CalibPars as calpars
Code Block
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':
 Code Block

    # 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'])

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):
 Code Block

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

Get array of calibration parameters of specific type:
 Code Block

    peds_arr = calib.getCalibPars('pedestals')

Get CSPAD2x2 data array from hdf5 file:
 Code Block

import HDF5Methods as hm 
    fname  = '/reg/neh/home1/dubrovin/LCLS/HDF5Analysis-v01/PyCSPadImage/src/mec73313-r0180.h5
    dsname = '/Configure:0000/Run:0000/CalibCycle:0000/CsPad2x2::ElementV1/MecTargetChamber.0:Cspad2x2.1/data'
    data_arr = hm.getDataSetForOneEvent(fname, dsname, event=0)

Get CSPAD2x2 data array from hdf5 file:
 Code Block

import GlobalGraphics as gg
    my_range = None
    my_range = (-10,40)
    gg.plotImageLarge(img2d, range=my_range)        
    gg.plotSpectrum(img2d, range=my_range)
    gg.show()
