Name | Direction | Type | Default | Description |
---|---|---|---|---|
Filename | Input | list of str lists | Mandatory | The name of the flood run file(s) to read. Multiple runs can be loaded and added together, e.g. INST10+11+12+13.ext. Allowed extensions: [‘.nxs’, ‘.raw’, ‘.sav’, ‘.n*’, ‘.s*’, ‘.add’, ‘.nxspe’] |
StartSpectrum | Input | number | Optional | Start value of the fitting interval |
EndSpectrum | Input | number | Optional | End value of the fitting interval |
ExcludeSpectra | Input | dbl list | Spectra to exclude | |
RangeLower | Input | number | Optional | The lower integration limit (an X value). |
RangeUpper | Input | number | Optional | The upper integration limit (an X value). |
CentralPixelSpectrum | Input | number | Optional | A spectrum number of the central pixel. |
Background | Input | string | Linear | Background function. Allowed values: [‘Linear’, ‘Quadratic’] |
OutputWorkspace | Output | MatrixWorkspace | Mandatory | The flood correction workspace. |
The algorithm takes a measured flood run (or runs) and converts it to a workspace that can be used for flood correction of reflectometry measurements. If StartSpectrum and EndSpectrum are given then they specify a range of detectors for which the flood will be calculated, for all other detectors it will be assumed 1. For detectors given in the ExcludeSpectra property the flood value will be set to a very large number that will have an effect of excluding these detectors from analysis.
If CentralPixelSpectrum is given then the integrated value of that spectrum is used to scale the flood workspace. If it is default then the Background property specifies the function to use to remove the background and scale the flood values. The integration range can be specified with the RangeLower and RangeUpper properties.
The output workspace shares the instrument with the inputs but not the logs.
