Description
In testing the effects in #164, I ran a simple search with a high cutoff such that I only detected a single source. When it plotted the map, I got the PGPLOT error saying the grayscale limits were equal (meaning I think there was no non-zero values in the map).
I don't know why this would be the case - needs chasing up.

The detection map was fine (it didn't appear to have anything in it as the source was small compared to the field of view...)
The moment map was failing because the calculation only works it out for non-blank spatial pixels, which were so judged on the basis of the first channel. This actually ruled out the location of the one source detected.
I've removed that criterion, as we later only do the calculation for detected pixels/voxels anyway, so the first check was unnecessary.
Works fine with that test case, so closing.
This applies to just the detection & moment maps - the moment map in the spectra plot is fine.
