ILL ¶

LoadILLSANS is upgraded to load the modern nexus files from instruments D11, D22 and D33 at the ILL.
SANSMask is extended to have a MaskedWorkspace property, to copy the mask from.

A string of wavelength ranges can now be specified. A reduction is then done for each wavelength range.

Transmission workspaces are now output by default from the new GUI.
The Beam centre finder now takes the default radius limits from the instrument parameter file if specified.
Updated old backend to mask by detector ID rather than spectrum number, improving reliability.
Added EventSlice option to options column in new GUI.
Added thickness column to table in new GUI.
Added Radius Cutoff and Wavelength Cutoff boxes to the old and new GUI.
Improved error messages in the new GUI to be more obvious and clearer.
Updated the naming of workspace groups in a sliced reduction.
Updated old backend to mask by detector ID rather than spectrum number, improving reliability.
NXcanSAS is now saved out with a .h5 extension so it can be read into SASView.

The beam stop arm is now masked on LOQ for the new backend.
Fixed a bug in the old backend where for LOQ the high angle bank was not being centered correctly in some cases.
User files specified in the batch file are now being loaded into the new GUI.
The new sans GUI will now save out all the outputs of a time sliced reduction.
Fixed a bug where save_format was not being specified if a user file was entered for a row.
Use gravity now defaulting to false.
MASK/TIME and TIME/MASK now both work in new backend.
SET Centre/HAB command is now correctly parsed into a separate variable to SET Centre.

Removed SaveNist as an option from both GUI’s
The Q range option on the beam centre tab was producing erroneous results so has been removed until it can be improved and fixed.
