SQW2 incorrect handling of non-recorded or masked data

Description
slices through a sqw2 plot show dips around areas of non-recorded data. This should not happen as these areas should not contribute at all.
Is this just a case of masking these bins?

Refs #4202. Better handling of theta widths in SofQW2.
Needs verification and error handling + parallelization.

Just thought I would let you know that this goes back to giving me all zeros.
comment:8 Changed 9 years ago by Stuart Campbell
It's just BASIS that gives zeros - I presume it is because some of our detectors don't have an Efixed associated with them. I think it would be ok to just mask these out.

Refs #4202. Fix normalisation of SofQW2
Also fix SofQW for new BASIS definition where some detectors have no efixed.

Refs #4202 Refs #4683. Merge much of code for Rebin2D & SofQW2
This solves the edge effect issue for Rebin2D and SofQW2 should now be correctly normalised.

Using MAR11001.raw, loaded, converted to dE, rebinned then ran SofQW2. Then ran transpose, and just plotted various spectra.
The 1d line plot shows the data going to zero in the gaps between detectors banks.
