Direct Geometry Changes¶
The instrument geometry of PANTHER has been corrected according to the findings during the hot commissioning.
New IDF has been added for the SHARP time-of-flight spectrometer at the ILL.
An estimation of fit parameters is performed when extracting a single tube for the first time. The estimate can subsequently be updated using the
Backgroundclass can now accept a list of functions through the
functionskeyword. This allows more than two functions to be used for the
Backgroundof a CrystalField fit.
Function parameters in the
Backgroundof a CrystalField fit can be fixed to their current values.
cf.background = Background(functions=[Function('Gaussian',Sigma=0.05313/2, Height= 1279300,PeakCentre=-0.0021), Function('Gaussian',Sigma=0.1111/2, Height= 1465,PeakCentre=0.09147), Function('LinearBackground', A0=34, A1=0.01)]) # Ties can then be applied by indexing to the relevant function cf.background.functions.ties(Height=1465, Sigma=0.1111/2, PeakCentre=0.09147) # Fixes the PeakCentre and Height of the first Gaussian to their current values. cf.background.functions.fix('PeakCentre', 'Height') # Fixes all the parameters of the LinearBackground to their current values. cf.background.functions.fix('all')
A bug has been fixed in the Crystal Field Python Interface where ties were not being applied properly for cubic crystal structures.
A bug has been fixed in the CrystalFieldFunction which prevented it working with the Trust Region minimizer.
A bug has been fixed in the LoadCIF algorithm caused when a .cif file has 2 sections, with the first not having the required data keys.
Widgets have been rearranged into groups of items based on their logical function
A bug has been fixed prevented the selection of more than one workspace for workspace addition.
A bug has been fixed in MSlice that caused a crash by ignoring the workspace selected by default for subtracting workspaces.
A bug has been fixed in MSlice that caused a crash when entering unexpected values into the width box for cuts.
A bug has been fixed that ignored the workspace selected by the user when subtracting workspaces.
