SANS: Geometrical corrections to path length

Reported by: Russell Taylor Owned by: Gesner Passos
Priority: trivial Milestone: Release 3.2
Component: SANS Keywords:
Cc: Blocked By:
Blocking: Tester: Anders Markvardsen

Description

For detectors at higher angles (i.e. LOQ HAB and both SANS2d detectors), we need to include corrections to the path length both in the sample and in individual detector pixels.

From meeting with Richard/Steve.

Would be nice to correct for at some stage. When this relevant will likely split this ticket up into several steps

1) Masking for big jaws

2) Algorithm to handle parallax errors, which if I understood this correctly is a coordinate error due to neutrons which are coming in at an angle may get absorbed at different 'positions' depending on wavelength of neutrons

3) Path through flat sample and path through detector strip may vary - relevant for high angle and this will affect intensities.

I suggest closing this ticket. It does not seem to be something that they are looking for now. When time comes to implement this, it will be raised again.
