Algorithms of This note describes raw intensity correction algorithms in the method Detector.calib method depends and their variation on detector type, as explained in this note.
det.calib algorithms
.
det.calib algorithms
Generic form of this method is
arr = det.calib(evt, cmpars=None, mbits=None, **kwargs)
Regular sequence of applied algorithms
- pedestals subtraction
- common mode correction depending on cmpars
- gain correction with gain factors from calib/.../pixel_gain
- apply mask depending on **kwargs
Mask
for all detectors excluding epix10ka and Jungfrau parameter mbits is deprecated, use **kwargs and algorithms from method mask_v2 from AreaDetector.
