Syntax
Qm = sw_econtract(Q,Name,Value)
Description
Qm = sw_econtract(Q,Name,Value)
converts \((Q,E)\) values in the phase
space into \(Q\) values as it would appear when measuring it with via
neutron diffraction.
Input Arguments
Q
- Input values in reciprocal space in the scattering plane in Å\(^{-1}\) units, dimensions are \([2\times n_Q]\).
Name-Value Pair Arguments
'E'
- Energy transfer value in meV, default value is zero.
'lambda'
- Wavelength of the incident neutron beam in Å.
'ki'
- Momentum of the incidend neutron beam in Å\(^{-1}\), alternative
input to
lambda
. 'sense'
- Scattering sense:
1
detectors are on the right hand side from the incident beam direction, default.-1
detectors are on the left hand side from the incident beam direction.
