Diffraction Changes¶

Powder Diffraction ¶

HFIR MIDAS instrument definition added
Support Pawley refinement of TOF workspaces in PawleyPattern1D class and added TOF peak profile BackToBackGauss for back-to-back exponential convoluted with a Gaussian.
Support zero shift and scale factor for reflection d-spacings in PawleyPattern1D class (equivalent to modifying TZERO and DIFC).
Now when using the spliiter workspace with AlignAndFocusPowderSlim it will output multiple workspaces, one for each target. The SplitterTarget property has been removed.

Disabled StripVanadiumPeaks in ref:SNSPowderReduction <algm-SNSPowderReduction>’s test, “SNSPowderRedux.PG3Analysis” because it was causing stochastic test failures on ornl runners and contributed little to the test’s purpose.
Solve the crash issue in ref:SNSPowderReduction <algm-SNSPowderReduction> regarding the definition of non-standard sample and container geometries for the absorption correction purpose.

Update to the Engineering Diffraction interface, adding two tabs, Absorption Correction and Texture.
The new Absorption Correction tab allows the user to correct workspaces for the beam attenuation through the sample.
The new Texture tab allows the user to combine data from focused workspaces and peak fitting, to plot pole figures for their experimental data
Basic usage of these tabs as part of a texture analysis reduction pipeline has been documented in the Texture Technique Documentation

Updated the Focus tab processing in the Engineering Diffraction interface to use CropWorkspaceRagged in order to remove zeros outside the data limits.
