This package contains python modules which work with both frameworks pyana and psana. Functionality of many modules resembles package ImgAlgos

See also Examples for package py_img_algos

Module py_img_algos.cspad_arr_producer

This module gets data from evt store for CSAPD or CSPAD2x2 depending on unique detector name in parameter source, produce numpy array of full scale shape (4,8,185,388) or (185, 388, 2) of specified in dtype type, and saves it in the evt store with unique name key_out. In case of missing 2x1 sections, their pixel amplitudes substituted by the value form val_miss.

Module py_img_algos.tahometer

Is intended to print records showing job performance current and integrated from the beginning of job:

calib_dir

cspad_array

string

keyword for input numpy array, shape=(4, 8, 185, 388) - for cspad or (185, 388, 2) - for cspad2x2

key_out

cspad_image

module verbosity:

  • =0 - print nothing
  • +1 - input pars (in __init__)

Module py_img_algos.image_save_in_file

This module gets from evt store 2-d image numpy array for specified unique name in key_in and saves it in the file with name given by parameter ofname. File extension defimes the output file format. Run and event numbers are added to the name of the output file. For example, for ofname = image.tiff files will be created with names image-r####-ev######.tiff, where symbols # stands for number.
