Reflectometry Changes¶

Table of Contents

Geometry for INTER has a small correction for the value of one of the attributes that was being interpreted as zero.

Algorithms ¶

SpecularReflectionPositionCorrect v2 - fixed a bug where entering an invalid detector or sample name would cause a segmentation fault.
The SpecularReflectionPositionCorrect v2 algorithm has a new property, DetectorCorrectionType, which specifies whether detector positions should be corrected by a vertical shift (default) or by a rotation around the sample position.
ReflectometryReductionOneAuto v2 and CreateTransmissionWorkspaceAuto v2 attempts to populate properties StartOverlap and EndOverlap with values from the IDF.
GroupDetectors v2 peforms a more resilient validation of grouping pattern that is less likely to throw an exception.

ReflectometryReductionOneAuto v2 - fixed a bug where processing instructions were not applied correctly to the specified transmission run.
ReflectometryReductionOne v2 and ReflectometryReductionOneAuto v2 have a new property, SummationType, which specifies whether summation should be done in wavelength (default) or in Q. For summation in Q, there is an additional new property, ReductionType, which should be used to specify whether the reduction is for a divergent beam or non-flat sample.

Interface ISIS Reflectometry (Polref) has been renamed to ISIS Reflectometry.
Fixed a bug that incorrectly allowed table workspaces to appear in the list of workspaces in the Save ASCII tab.
Fixed a bug where the contents of the processing table where not saved to the selected table workspace.
Added two new buttons Expand Groups and Collapse Groups which expand and collapse all groups in the table respectively.
Fixed a bug when removing rows from the processing table.
Fixed a bug where if either Instrument and/or Experiments was disabled, their respective entries would still be applied in the reduction.
Fixed shortcuts:
- Ctrl+C copies the selected row(s) to the clipboard.
- Ctrl+V pastes the contents of the clipboard into the selected row(s). If no rows are selected, new ones are added at the end.
- Ctrl+X copies the selected row(s) to the clipboard and deletes them.
A brief description about the columns in the table can be now accessed by using the What’s this tool (last tool in the toolbar) and clicking on the column headers.
Added three more time slicing options in the ‘Event Handling’ tab for analysing event data - Uniform Even, Uniform and Log Value slicing.
For custom slicing (and new slicing options), workspace slices are now identified by an index (e.g. ws_slice_0) instead of a start/stop value.
The ‘Get Defaults` button for ‘Experiment Settings’ in the ‘Settings’ tab now populates StartOverlap and EndOverlap text boxes with values from the IDF.
