Summary

Converts polynomial factors to histograms with polarization efficiencies.

Properties

Name Direction Type Default Description
InputWorkspace Input MatrixWorkspace Mandatory An input workspace to use the x-values from.
Pp Input dbl list   Effective polarizing power of the polarizing system. Expressed as a ratio 0 < Pp < 1
Ap Input dbl list   Effective polarizing power of the analyzing system. Expressed as a ratio 0 < Ap < 1
Rho Input dbl list   Ratio of efficiencies of polarizer spin-down to polarizer spin-up. This is characteristic of the polarizer flipper. Values are constants for each term in a polynomial expression.
Alpha Input dbl list   Ratio of efficiencies of analyzer spin-down to analyzer spin-up. This is characteristic of the analyzer flipper. Values are factors for each term in a polynomial expression.
P1 Input dbl list   Polarizer efficiency.
P2 Input dbl list   Analyzer efficiency.
F1 Input dbl list   Polarizer flipper efficiency.
F2 Input dbl list   Analyzer flipper efficiency.
OutputWorkspace Output MatrixWorkspace Mandatory An output workspace.

Description

Creates a workspace in which the spectra contain the polarization efficiencies calculated from polynomial coefficients on the x-values of the input workspace.

Usage

Example

ws = CreateWorkspace([0, 1, 2, 3, 4], [0, 0, 0, 0, 0])
eff = CreatePolarizationEfficiencies(ws, Pp=[0, 1, 2, 3], Ap=[1, 2, 3], Rho=[3, 2, 1], Alpha=[4, 3, 2, 1])
print(eff.getAxis(1).label(0))
print(eff.getAxis(1).label(1))
print(eff.getAxis(1).label(2))
print(eff.getAxis(1).label(3))

Output:

Pp
Ap
Rho
Alpha
