Rebin each spectrum of a workspace independently. There is only one delta allowed per spectrum
Name | Direction | Type | Default | Description |
---|---|---|---|---|
InputWorkspace | Input | MatrixWorkspace | Mandatory | input workspace |
OutputWorkspace | Output | MatrixWorkspace | Mandatory | output workspace |
XMin | Input | dbl list | minimum x values with NaN meaning no minimum | |
XMax | Input | dbl list | maximum x values with NaN meaning no maximum | |
Delta | Input | dbl list | step parameter for rebin | |
PreserveEvents | Input | boolean | True | False converts event workspaces to histograms |
This is a workflow algorithm that rebins each spectrum of a workspace independently. This is intended for workspaces with a relatively small number of spectra (e.g. <10), but places no restrictions on the input workspace.
The minimum and maximum values that are specified are interpreted as follows:
numpy.nan
, math.nan
, and np.inf
are interpreted to mean use the data’s minimum or maximum x-value.The Delta
parameter is required and can either be a single number which is common to all, or one number per spectra.
Positive values are interpreted as constant step-size. Negative are logorithmic.
Note
To run these usage examples please first download the usage data, and add these to your path. In Mantid this is done using Manage User Directories.
This is an example of how RebinRagged
would be used near the end of a workflow to generate a real-space distribution of data after it had been reduced into a number of “banks” or “spectra.”
As mentioned above, numpy.nan
or math.nan
can both be used.
This particular use-case, which uses the input workspace’s binning, could be done with CropWorkspaceRagged with similar results.
from numpy import nan
NOM_91796 = LoadNexusProcessed(Filename='NOM_91796_banks.nxs')
RebinRagged(InputWorkspace=NOM_91796, OutputWorkspace='cropped',
Xmin=[0.67, 1.20, 2.42, 3.70, 4.12, 0.39],
Delta=0.02,
Xmax=[10.20, 20.8, nan, nan, nan, 9.35])
