Method calib.getCalibPars(type, run)
allows to get array of calibration parameters of for specific type and run number, for example
Code Block |
---|
peds_arr = calib.getCalibPars('pedestals',123)
|
returns the pedestals (numpy) array with data-like shape (185, 388, 2).

Depending on experimental requirements, there may be different methods of how to generate image. For example we use a simple 2-d histogram technique.
The CSPAD2x2 image can be obtained from the pixel coordinate and intensity arrays (of the same shape) by call:
img2d = pixcoorgg.getImagegetImageFromIndexArrays(X,Y,arr)
Plot image and its spectrum

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