SANS Changes¶

New Features ¶

The Compatibility Mode feature in the ISIS SANS GUI is no longer selected by default. This feature should be considered deprecated and will be removed completely in a future release.

New algorithm PolarizerEfficiency for calculating the efficiency of a polariser.

Fix the calculation in algorithm HeliumAnalyserEfficiency v1 to calculate the efficiency using the mid-point of the wavelength bins. The error calculation now also propagates the uncertainty in the wavelength.
Event binning tooltips have been improved to clarify Compatibility Mode and the effect of leaving the text entry blank.
The plot results checkbox is now hidden by default to prevent issues when both scaling and plot results are enabled. You can enable it via your properties file if needed. This change will help us decide whether to keep it hidden or fix the underlying issue.
The Optimize Event Slices checkbox has been removed from the General, Scale, Event Slice, Sample settings on the ISIS SANS Settings menu to avoid an issue with the SANSSingleReduction2 algorithm not working.
The ISIS SANS Beam centre tab no longer crashes when no direction checkbox is selected. Also improved the error message when this happens.
