PolarizationEfficiencyCor v1¶

Summary ¶

Corrects a group of polarization analysis workspaces for polarizer and analyzer efficiencies.

Properties ¶

Name	Direction	Type	Default	Description
InputWorkspaces	Input	str list		A list of names of workspaces to be corrected.
InputWorkspaceGroup	Input	WorkspaceGroup		A group of workspaces to be corrected.
CorrectionMethod	Input	string	Wildes	Correction method. Allowed values: [‘Wildes’, ‘Fredrikze’]
Efficiencies	Input	MatrixWorkspace	Mandatory	A workspace containing the efficiency factors as histograms: P1, P2, F1 and F2 in the Wildes method and Pp, Ap, Rho and Alpha for Fredrikze.
Flippers	Input	string		Flipper configurations of the input workspaces (Wildes method only). Allowed values: [‘’, ‘00, 01, 10, 11’, ‘00, 10, 11’, ‘00, 01, 11’, ‘00, 11’, ‘0, 1’, ‘0’]
SpinStatesOutWildes	Input	string		The order of the spin states in the output workspace. (Wildes method only).
PolarizationAnalysis	Input	string		What Polarization mode will be used? PNR: Polarized Neutron Reflectivity mode PA: Full Polarization Analysis PNR-PA (Fredrikze method only). Allowed values: [‘’, ‘PA’, ‘PNR’]
SpinStatesInFredrikze	Input	string		The order of spin states in the input workspace group. The possible values are ‘pp,pa,ap,aa’ or ‘p,a’. (Fredrikze method only).
SpinStatesOutFredrikze	Input	string		The order of spin states in the output workspace group. The possible values are ‘pp,pa,ap,aa’ or ‘p,a’. (Fredrikze method only).
OutputWorkspace	Output	WorkspaceGroup	Mandatory	A group of polarization efficiency corrected workspaces.

Description ¶

This is a wrapper around the algorithms PolarizationCorrectionWildes v1 and PolarizationCorrectionFredrikze v1. Use CorrectionMethod property to select between the two. The default is Wildes.

The input workspaces can be passed in either via InputWorkspaces or InputWorkspaceGroup property but not both. An attempt to set both properties will result in an error.

The default values for the Flippers, SpinStates, and PolarizationAnalysis properties are empty strings and correspond to the actual defaults of the child algorithms.
