============= Muon Analysis ============= .. contents:: Table of Contents :local: Interfaces ---------- ALC ### - Choosing *run_start* or *run_end* as the log value will now work correctly - the values are taken as seconds relative to the start time of the first run. Muon Analysis ############# Multi-dataset fitting ********************* The *Data Analysis* tab of the Muon Analysis interface has been updated to enable simultaneous fits of multiple datasets. A full explanation of how to use this new functionality is contained in the interface's documentation. Results tables of these new kinds of fit can also be created. As this is a new change for this release, please report any bugs, or requests for enhancements, to the development team. If you find a bug that stops you working, or would simply prefer to stick with the previous UI, just check the "Compatibility mode" box on the *Settings* tab and this will revert the interface to how it was in Mantid 3.7. Other fixes and enhancements: ***************************** - When reusing the same plot window, an option has been added on the Settings tab to control how many previous fits are kept. It can be adjusted to 0 (remove all previous fits; default pre-Mantid 3.7), 1 (keep just one previous fit plus this one; new default) or higher. - *run_start* and *run_end* are now available as log values to use in the results table. They can be inserted either as text (ISO-formatted date strings) or as seconds since the start of the first run. - Documentation has been moved to the Mantid help system. - A bug was fixed where, when plotting the log of counts and then switching to plot counts or asymmetry, the y axis was left as a logarithmic axis. Algorithms ---------- - :ref:`MaxEnt `: MaxEnt has a new property, *ComplexImage*, which can be set to *False* when the imaginary part of the image should not be taken into account for the calculations. - :ref:`MaxEnt `: The expression for the second derivative of real (pos/neg) images has been corrected. - :ref:`MaxEnt `: The reconstructed image is always a point data workspace. The reconstructed data is of the same type as the input workspace. - :ref:`CalMuonDetectorPhases `: the *Frequency* parameter is now supplied in MHz rather than megaradians per second. - :ref:`CalMuonDetectorPhases `: The first column of the output phase table now shows spectrum numbers rather than workspace indices. - :ref:`PlotAsymmetryByLogValue `: If *run_start* or *run_end* are chosen as the log to use, the values are taken as seconds relative to the start time of the first run. - :ref:`LoadMuonNexus `: Fixed loading of certain v1 NeXus files converted from other formats that did not contain number of good frames. - :ref:`LoadMuonNexus `: Now loads the correct detector IDs, whether the whole file is loaded or just a selection of spectra. Correctly handles muon v2 Nexus files, in which one spectrum can map to multiple detectors. Fit Functions ------------- - :ref:`Keren `: A bug was fixed so that the field comes out in the correct units. | `Full list of changes `_ on GitHub.
