Monitor normalization has been refactored. An improvement in performance of a factor x3 has
been observed when the reduction is performed with no monitor normalization.
The monitor and detectors of interest are first extracted from the input workspace before being converted to
wavelength. This fixes a problem by which the first monitor was distorting the rest of the data due to
AlignBins in ConvertUnits v1.
When CorrectionAlgorithm was set to AutoDetect the algorithm was not able to find polynomial
corrections, as it was searching for polynomial instead of polystring.
When a correction algorithm was applied, monitors were integrated if NormalizeByIntegratedMonitors
was set to true, which is the default. In the new version of the algorithms, monitors will never be integrated if a correction algorithm
is specified, even if NormalizeByIntegratedMonitors is set to true.
Fix some problems when moving the detector components in the instrument. The new versions use ProcessingInstructions
to determine which detector components need to be moved. Detectors will be moved to an angle if is
specified. If is not provided, detectors will not be moved.
Monitor integration range was not being applied properly to CRISP data. The problem was that in the parameter
file the wavelength range used to crop the workspace in wavelength is [0.6, 6.5] and the monitor integration
range is outside of these limits ([4, 10]). This was causing the algorithm to integrate over [0.6, 4].
ReflectometryReductionOneAuto v3 now outputs three workspaces: a workspace in wavelength, a workspace in Q with native binning,
and a rebinned and scaled workspace in Q. The latter is rebinned according to MomentumTransferMin, MomentumTransferMax
and MomentumTransferStep. If these are not provided, the algorithm will attempt to determine the bin width
running CalculateResolution <http://docs.mantidproject.org/v3.9.0/algorithms/CalculateResolution-v1.html>. When this is not possible, the rebinning will not take place.
Stitch1D v3 documentation has been improved, it now includes a workflow diagram illustrating
the different steps in the calculation and a note about how errors are propagated.
Stitch1DMany has a new property, ScaleFactorFromPeriod, which enables it to apply
scale factors from a particular period when stitching multi-period runs. Its documentation has also been
updated and improved, including more detail on algorithm properties and adds a workflow description and diagram.
ConvertToReflectometryQ v1 corrects the detector position before performing any type of calculation.
Detectors are corrected to an angle read from the log value stheta.
INTER parameter file was updated. The monitor background range, wavelength range and point detector range were updated,
and two additional properties, TransRunStartOverlap and TransRunEndOverlap, that specify the integration range
to be used by Stitch1D v3, have been added.
OFFSPEC parameter file was updated with TransRunStartOverlap and TransRunEndOverlap
POLREF parameter file was updated with a new monitor background range, point detector range and parameters
TransRunStartOverlap and TransRunEndOverlap.
SURF parameter file was updated with a new multi detector range.
A new tab, ‘Event handling’ has been added. This tab allows users to select custom time slices to analyze event data.
A new tab, ‘Settings’ has been added. This tab displays global options for experiment and instrument settings.
A new tab, ‘Save ASCII’ has been added. This tab is similar in function and purpose to the ‘Save Workspaces’ window accessible from Interfaces->ISIS Reflectometry->File->Save Workspaces.
The interface is now arranged in two different groups. Groups apply to tabs ‘Run’, ‘Event Handling’ and ‘Settings’.
When runs are transferred to the processing table groups are now labeled according to run title.
StartOverlap and EndOverlap are used to calculate the integration range in Stitch1DMany v1, when specified.
Column dQ/Q is used as the rebin parameter to stitch workspaces.
An issue by which the interface was not populating dQ/Q, Qmin and Qmax correctly for multi-period datasets has been fixed.
A shift in Y between different slices has been fixed.
When the instrument is changed from the GUI, the Mantid default instrument is updated accordingly.
Error messages are displayed if the user either attempts to transfer zero runs or transfer runs with a different strategy to the one they used to search for runs with.
Fixed a bug where if the user answered ‘no’ to a popup asking if they wanted to process all runs, the progress bar would show activity as though a data reduction was occurring.
Documentation regarding the interface has been updated accordingly.
