|---|---|---|---|---|
| SpectraFile | Input | string | Mandatory | Incident spectrum and detector efficiency correction file. Allowed extensions: [‘.dat’] |
| OutputWorkspace | Output | MatrixWorkspace | Mandatory | An output Workspace containing spectra for each detector bank. |
| InputWorkspace | Input | MatrixWorkspace | Optional: An input workspace with the instrument we want to use. | |
| InstrumentName | Input | string | Optional: Name of the instrument to base the GroupingWorkspace on which to base the GroupingWorkspace. | |
| InstrumentFilename | Input | string | Optional: Path to the instrument definition file on which to base the GroupingWorkspace. Allowed extensions: [‘.xml’] |
Load incident spectrum and detector efficiency correction file containing spectra for each detector. The spectra are created by “TOPAZ_spectrum.py” from files of vanadium or TiZr and background.
