This algorithm is responsible for making the conversion from time-of-flight to energy transfer for direct geometry spectrometers. The diagram below shows the workflow for the algorithm. The SNS instruments have a log called EnergyRequest which allows the IncidentEnergyGuess parameter to be left blank. Also, SNS instruments need to pass a monitor workspace to GetEi since they are separate from the sample workspace. Parameters in italics are controlled by the instrument parameter file (IPF) unless provided to the algorithm via a property manager. The mappings are given below.
| Parameter | IPF Mapping |
|---|---|
| TibTofRangeStart | bkgd-range-min |
| TibTofRangeEnd | bkgd-range-max |
Parameters in italics with dashed perimeters are only controllable by
the IPF name given. All underlined parameters are fixed and not
controllable. The EnergyTransferRange parameter takes the canonical
Mantid notation of (start, step, stop). However, it can be left blank
and the following values will be used
.
The use of the SofPhiEIsDistribution parameter in the last Rebin call is used to set the Rebin algorithm parameter PreserveEvents.
Warning
This algorithm is not really intended for use at the command line, but is used within DgsReduction.
