Table of Contents
Adjusts the detector position based on a detector height and distance offset and normalizes with detector efficiency from a vanadium file or workspace, and converts the input to Q-space.
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Filename | Input | list of str lists | Input autoreduced detector scan data files to convert to Q-space. Allowed extensions: [‘.nxs.h5’, ‘.nxs’] | |
| VanadiumFile | Input | string | File with Vanadium normalization scan data. Allowed extensions: [‘.nxs’] | |
| InputWorkspaces | Input | string | Workspace or comma-separated workspace list containing input MDHisto scan data. | |
| VanadiumWorkspace | Input | IMDHistoWorkspace | MDHisto workspace containing vanadium normalization data | |
| DetectorHeightOffset | Input | number | 0 | Optional distance (in meters) to move detector height (relative to current position) |
| DetectorDistanceOffset | Input | number | 0 | Optional distance (in meters) to move detector distance (relative to current position) |
| Wavelength | Input | number | Optional | Optional wavelength value to use as backup if one was not found in the sample log |
| OutputAsMDEventWorkspace | Input | boolean | True | Whether to use ConvertHFIRSCDtoQ for an MDEvent, or ConvertWANDSCDtoQ for an MDHisto |
| MinValues | Input | dbl list | -10,-10,-10 | 3 comma separated values, one for each q_sample dimension |
| MaxValues | Input | dbl list | 10,10,10 | 3 comma separated values, one for each q_sample dimension; must be larger thanthose specified in MinValues |
| MergeInputs | Input | boolean | False | If all inputs should be merged into one MDEvent output workspace |
| BinningDim0 | Input | dbl list | -8.02,8.02,401 | Binning parameters for the 0th dimension. Enter it as acomma-separated list of values with theformat: ‘minimum,maximum,number_of_bins’. |
| BinningDim1 | Input | dbl list | -2.52,2.52,126 | Binning parameters for the 1st dimension. Enter it as acomma-separated list of values with theformat: ‘minimum,maximum,number_of_bins’. |
| BinningDim2 | Input | dbl list | -8.02,8.02,401 | Binning parameters for the 2nd dimension. Enter it as acomma-separated list of values with theformat: ‘minimum,maximum,number_of_bins’. |
| OutputWorkspace | Output | Workspace | Mandatory | Output MDWorkspace in Q-space, name is prefix if multiple input files were provided. |
Takes in DEMAND detector scan data from files or workspaces and converts them to Q-space, providing an optional adjustment of the detector positions. DetectorHeightOffset adjusts all banks along the y-axis, and DetectorDistanceOffset adjusts banks along the z-axis. Both parameters move the detector relative to the current detector position.
The output can be either an MDEventWorkspace or a MDHistoWorkspace. For a MDHistoWorkspace, the conversion to Q-space is done using ConvertWANDSCDtoQ while ConvertHFIRSCDtoMDE is used for outputting an MDEventWorkspace.
If multiple data file are included then the output will be a WorkspaceGroup contaning all the MDWorkspaces.
