Command examples
Script and its features
- Script
det_pixel_statusprocesses dark or light data and produces 2-d image or per-panel pixel status files. - Implemented algorithms, named here as Features after Ref.2,3, are developed in R&D with Chuck briefly documented in Ref.1.
- Tested for epix100a - other detectors not tested...
All algorithms/features are wrapped under the common hood of event processing loop and files' I/O. But, not all algorithms/features can be applied simultaneously due to different data types (dark or light) and different processing algorithms. Suggested combinations for -F parameters are shown in three examples below features with associated type of generated status constants in repository
