Mx-calibrate
usage: MX-Calibrate -w 1.54 -c CeO2 file1.cbf file2.cbf ...
Calibrate automatically a set of frames taken at various sample-detector distance. Return the linear regression of the fit in funtion of the samplesetector distance.

This tool has been developed for ESRF MX-beamlines where an acceptable calibration is usually present is the header of the image. PyFAI reads it and does a "recalib" on each of them before exporting a linear regression of all parameters versus this distance.
