Calibration constants
All detector calibration constants (np.array) and associated metadata (dict) are available through the dictionary det.calibconst with calibration type as a key. For example:

- False, edges=False, center=False, calib=False, umask=None) are set to define mask for pixel_status only.
- mask is used in det.raw.calib/image mask at evaluation of common mode correction, but by default it is not applied to data.
- to apply mask to data use multiplication calib *= mask.
