Module ImgAlgos::NDArrImageProducer

For any available in the event store ndarray<const T,NDim>, defined by the source and key_in parameters, and which size is equal to the number of pixels in the detector,  this module creates 2-d image ndarray<const TOUT,2> and saves it in the event store with key_out. TOUT is defined by the type_out. Pixel geometry array is retreived from the calibration file of  "geometry" type from default standard or specified in calibdir directory.

Configuration parameters:

source

""

input source of data

key_in

""

key for input data, for example it might be "calibrated", by default (empty) raw data

key_out"image"key for output image in the event store.
type_out"asinp"type of data in output image array. Possible values - "asinp"-the same type as input array, "int16", "float", "double", "int".

module verbosity:

  • =0 - print nothing
  • +1 - input pars
  • +2 - event record
  • +4 - beginning of 3 stages
  • +8 - processed statistics at the end of each stage
  • +16 - size of types table
  • +32 - summary with keywords for parser
  • +64 - statistics of bad pixels
  • +128 - mean and rms in 3 iterations of the threshold auto-evaluation algorithm and evaluated threshold
  • +256 - warning if ndarray shape is not defined yet

Module ImgAlgos::NDArrAverage

This module averages over events the per-element data of the image array (ndarray<const T,NDim>, where T is implemented for almost all types: int, int16, uint, float, double etc., NDim≤5) and saves files for sum, averaged, rms values, mask, and, the hot pixel map. Input ndarray can be specified by the source and key parameters. Averaging may have up to three stages, depending on configuration parameters:
