This module works on CSPad data array (shaped as \[5920=4*8*185\]\[388\]), uses the "median algorithm" to evaluate the signal and noise for each pixel, evaluates S/N ratio for each pixel, counts the fraction of events where {{S/N > SoNThr}}, and writes the same shape arrays for pixel mask and status information in the {{maskfile}} and {{statusfile}}, respectively. The {{statusfile}} contains for each pixel the fraction of events where {{S/N > SoNThr}}. This module presents a part of features implemented in the module [ImgAlgos::CSPadArrPeakFinder|PCDS:Psana Module Catalog#Module ImgAlgos::CSPadArrPeakFinder]. |

Module ImgAlgos::CSPadArrPeakFinder
| Wiki Markup |
|---|
This module extends features of the previous [ImgAlgos::CSPadArrNoise|PCDS:Psana Module Catalog#Module ImgAlgos::CSPadArrNoise] module for the case ofis intended for peak finding. It works on in CSPad data array (shaped as \[5920=4*8*185\]\[388\]. It extends features of the module [ImgAlgos::CSPadArrNoise|PCDS:Psana Module Catalog#Module ImgAlgos::CSPadArrNoise]) and works as follows: |
- in the constructor and
beginJob(...)method:- enters input parameters,
- (re)set the initial mask of noisy pixels from file
hot_pix_mask_file(if its name is specified in the configuration file), - do necessary initialization of work arrays.
