Message from James Lord via mantid help:

In a script I accidentally did:


Instead of the intended


(data from HiFi, spectra are numbered 1 to 64)

There was no error, but I got a very strange result
(asymmetry squashed close to 1.0 instead of the oscillation centred around zero
I was expecting).

Including non-existent spectra with negative numbers or
greater than the maximum available also doesn’t give any error and looks like
it just omits those from the forward or backward group.
