Convert from the detector vs scan index MDHistoWorkspace into a MDEventWorkspace with units in Q_sample.
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | IMDHistoWorkspace | Mandatory | An input workspace. |
| Wavelength | Input | number | Mandatory | Wavelength |
| MinValues | Input | dbl list | -10,-10,-10 | It has to be 3 comma separated values, one for each dimension in q_sample.Values smaller then specified here will not be added to workspace. |
| MaxValues | Input | dbl list | 10,10,10 | A list of the same size and the same units as MinValues list. Values higher or equal to the specified by this list will be ignored |
| SplitInto | Input | int list | 5 | A comma separated list of into how many sub-grid elements each dimension should split; or just one to split into the same number for all dimensions. Default 5. |
| SplitThreshold | Input | number | 1000 | How many events in a box before it should be split. Default 1000. |
| MaxRecursionDepth | Input | number | 20 | How many levels of box splitting recursion are allowed. The smallest box will have each side length \(l = (extents) / (SplitInto^{MaxRecursionDepth}).\) Default 20. |
| ObliquityParallaxCoefficient | Input | number | 1 | Geometrical correction for shift in vertical beam position due to wide beam. |
| OutputWorkspace | Output | MDEventWorkspace | Mandatory | An output workspace. |
This algorithm will convert the output of LoadWANDSCD v1 or the autoreduced data from DEMAND (HB3A) into a MDEventWorkspace in Q-sample, where every pixel at every scan point is converted to a MDEvent. This is similar to ConvertWANDSCDtoQ v1 except that it doesn’t histogram the data or do normalization. FindPeaksMD v1 can be run on the output Q sample space, then the UB can be found and used to then convert to HKL using ConvertWANDSCDtoQ v1 . IntegratePeaksMD v2 will also work on the output of this algorithm.
Example - ConvertHFIRSCDtoMDE
LoadWANDSCD(IPTS=7776, RunNumbers='26640-27944', OutputWorkspace='data',Grouping='4x4')
ConvertHFIRSCDtoMDE(InputWorkspace='data',
Wavelength=1.488,
OutputWorkspace='Q')
