The CalFile is a calibration file originally created for use in the Ariel powder diffraction data reduction package.
Files using this format with the .cal extension are still used by several algorithms in Mantid.
The file is a simple text file with the following format

number
: ignoredUDET
: detector IDoffset
: calibration offset used in AlignDetectors. Comes from the OffsetsWorkspace
, or 0.0
if none is given.select
: 1 if selected (use the pixel). Comes from the MaskWorkspace
,
or 1 if none is given.group
: what group to focus to in
DiffractionFocussing. Comes from the
GroupingWorkspace
, or 1 if none is given. Setting the group
as 0 specifies the detector as not to be grouped, effectively masking it.See here for information on CalFile in the greater context of time-of-flight powder diffraction calibration.
