StripPeaks v1¶

Summary ¶

This algorithm attempts to find all the peaks in all spectra of a workspace and subtract them from the data, leaving just the ‘background’.

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	The name of the input workspace.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	The name to use for the output workspace.
FWHM	Input	number	7	The number of points covered, on average, by the fwhm of a peak (default 7). Passed through to [[FindPeaks]].
Tolerance	Input	number	4	A measure of the strictness desired in meeting the condition on peak candidates, Mariscotti recommends 2 (default 4)
PeakPositions	Input	dbl list		Optional: enter a comma-separated list of the expected X-position of the centre of the peaks. Only peaks near these positions will be fitted.
PeakPositionTolerance	Input	number	0.01	Tolerance on the found peaks’ positions against the input peak positions. Non-positive value indicates that this option is turned off.
BackgroundType	Input	string	Linear	Type of Background. Present choices include ‘Linear’ and ‘Quadratic’. Allowed values: [‘Linear’, ‘Quadratic’]
HighBackground	Input	boolean	True	Flag to indicate that the peaks are relatively weak comparing to background.
WorkspaceIndex	Input	number	Optional	If set, will remove peaks only in the given spectrum of the workspace. Otherwise, all spectra will be searched.
MaximumChisq	Input	number	100	The maximum chisq value for fits to remove the peak. Default 100.
