Actually not sure anymore because the test is giving errors when the 2 bins are actually the same. also it happens for a non-tof test

can you paste some sample errors, for both TOF and non-TOF?

mh not sure than the shift is different then zero if we want to use them all

in fact, we don't support this yet, but having wrong code is a bad idea. Add a comment and throw an error if the argument isn't what we expect?

However, it seems hard to know what the argument should be. For 2 TOF bins, the max number of central should be 1. For 3 TOF bins, it should also be 1.5... (1 could work, but how would one say then we only want to do the central one). Looks like the name is still wrong.

Or remove...
