This algorithm is responsible for setting up the necessary workspaces to hand off to the DetectorDiagnostic algorithm. The diagram below shows the manipulations done by this algorithm. Workspaces that have dashed lines are optional. Parameters in italics are retrieved from the instrument parameter file (IPF) unless they are provided to the algorithm via a property manager. The mappings for these parameters are shown below.

Parameter	IPF Mapping	DetectorDiagnostic Mapping
RejectZeroBackground	diag_samp_zero	-
BackgroundCheck	check_background	-
PsdBleed	diag_bleed_test	-
BackgroundTofStart	bkgd-range-min	-
BackgroundTofEnd	bkgd-range-max	-
DetVanRatioVariation	diag_variation	DetVanRatioVariation

The open circles represent groups of parameters. They are detailed in the tables below. All parameters given here act like italicized parameters.
