 Example for Module ImgAlgos::AcqirisCalib

Module ImgAlgos::AcqirisCFD

• Gets Acqiris waveforms from event store as ndarray<double,2> object using parameters source, key_wform, key_wtime;
• runs constant-fraction discriminator algorithm on all acqiris channels using user-specified per-channel parameters;

• saves edges into the event as a set of ndarray<double,1>;

  
  

  parameter	default value	description
  source	"DetInfo(:Acqiris)"	Source of data.
  key_wform	"acqiris_wform"	Key for input ndarray with waveforms (either raw, or subtracted using AcqirisCalib module) from evt store.
  key_wtime	"acqiris_wtime"	Key for input ndarray with waveform times from evt store.
  key_edges	"acqiris_edges_"	Key for output ndarray<double,1> with calibrated waveforms. This key will have the acqiris channel number (1 thru 20) appended to the end of it, and the data for that channel will be added to the event only if edges were found.
  baselines	""	A list of baseline values (one per channel) to subtract from the waveform in volts.
  fractions	""	A list of fractions (one per channel) between 0 and 1. The edge-time reported will be at the time when the pulse is at this fraction of the peak value.
  thresholds	""	A list of threshold values (one per channel) in volts that indicate a new edge should be found. If this value is less than the baseline, then the algorithm will look for negative pulses, otherwise it will look for positive pulses.
  deadtimes	""	A list of deadtimes (one per channel) in seconds. After each edge the algorithm will ignore any new hits in this time interval.
  leading_edges	""	A list of 0/1 values (one per channel) indicating whether edge-times are desired for leading edges (1) or falling edges (0).

Module ImgAlgos::ImgAverage

This module averages over events the per-pixel data of the image array (ndarray<double,2>) and saves files for averaged, rms values, and, if requested, the hot pixel mask. Input data can be specified by the source and key parameters. Averaging may have up to three stages, depending on configuration parameters:
