pyimgalgos

This package contains python modules which work with both frameworks pyana and psana. Functionality of these modules resembles modules from C++ package ImgAlgos. The difference between two frameworks at code level is explained in Migration from pyana to psana.

Module

...

pyimgalgos.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.

pyimgalgos.cspad_image_producer

This module gets from evt store the numpy array identified by key_in of full scale shape (4,8,185,388) or (185, 388, 2) for CSPAD or CSPAD2x2, respectively, and produces 2-d image numpy array, taking into account geometry calibration parameters specified by the path calib_dir. The output image array is saved in the evt store with unique name, specified by parameter key_out.

pyimgalgos.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 defines the output file format. Experiment, 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-<experinent>-r####-ev######.tiff, where symbols # stands for numbers.

pyimgalgos.tahometer

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

py_img_algospyimgalgos.tahometer: run:0049  evt:000005  t[sec]:     2.575  dt[sec]:     2.575  n/t[1/sec]:     1.942  dn/dt[1/sec]:     1.942
