MaskedWorkspace(Input) MatrixWorkspace If given but not as a SpecialWorkspace2D, the masking from this workspace will be copied. If given as a SpecialWorkspace2D, the masking is read from its Y values.[]

ForceInstrumentMasking(Input) boolean Works when ‘MaskedWorkspace’ is provided and forces to use spectra-detector mapping even in case when number of spectra in ‘Workspace’ and ‘MaskedWorkspace’ are equal

StartWorkspaceIndex(Input) number If other masks fields are provided, it’s the first index of the target workspace to be allowed to be masked from by these masks, if not, its the first index of the target workspace to mask. Default value is 0 if other masking is present or ignored if not.

EndWorkspaceIndex(Input) number If other masks are provided, it’s the last index of the target workspace allowed to be masked to by these masks, if not, its the last index of the target workspace to mask. Default is number of histograms in target workspace if other masks are present or ignored if not.

rebin(InputWorkspace, Params, PreserveEvents=None, FullBinsOnly=None, IgnoreBinErrors=None, UseReverseLogarithmic=None, Power=None, BinningMode=None)

Rebins data with new X bin boundaries. For EventWorkspaces, you can very quickly rebin in-place by keeping the same output name and PreserveEvents=true.

Property descriptions:

InputWorkspace(Input:req) MatrixWorkspace Workspace containing the input data

OutputWorkspace(Output:req) MatrixWorkspace The name to give the output workspace

Params(Input:req) dbl list A comma separated list of first bin boundary, width, last bin boundary. Optionally this can be followed by a comma and more widths and last boundary pairs. Optionally this can also be a single number, which is the bin width. In this case, the boundary of binning will be determined by minimum and maximum TOF values among all events, or previous binning boundary, in case of event Workspace, or non-event Workspace, respectively. Negative width values indicate logarithmic binning.

PreserveEvents(Input) boolean Keep the output workspace as an EventWorkspace, if the input has events. If the input and output EventWorkspace names are the same, only the X bins are set, which is very quick. If false, then the workspace gets converted to a Workspace2D histogram.

FullBinsOnly(Input) boolean Omit the final bin if its width is smaller than the step size

IgnoreBinErrors(Input) boolean Ignore errors related to zero/negative bin widths in input/output workspaces. When ignored, the signal and errors are set to zero

UseReverseLogarithmic(Input) boolean For logarithmic intervals, the splitting starts from the end and goes back to the start, ie the bins are bigger at the start getting exponentially smaller until they reach the end. For these bins, the FullBinsOnly flag is ignored.

Power(Input) number Splits the interval in bins which actual width is equal to requested width / (i ^ power); default is linear. Power must be between 0 and 1.

BinningMode(Input) string Optional. Binning behavior can be specified in the usual way through sign of binwidth and other properties (‘Default’); or can be set to one of the allowed binning modes. This will override all other specification or default behavior.[Default, Linear, Logarithmic, ReverseLogarithmic, Power]
