A calibration file is needed to merge data collected from each of 11-BM 12 detectors into a single 2theta vs intensity dataset.

The calibration file corrects each of the 12 detectors for 2theta zero shift, wavelength, and scaling factor.

Calibration files are obtained from a 12-histogram GSAS refinement of data collected on a powder sample containing a mixture of NIST SRM Al2O3 & Si.

The standard calibration scan parameters at 30 keV currently are as follows:
