Description

Used in the Liquids Reflectometer reduction at the SNS, this algorithm computes the primary fraction (aka ‘clocking correction’) for the given data. The primary fraction is the fraction of the counts within a specified range that should contain the reflected beam to the total number of counts on the detector.
