NAME

       MX-Calibrate  -  calibrate  the  distance  of  a detector from a set of powder diffraction
       patterns

DESCRIPTION

       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.
