LC issue - cannot do a non-empty take from an empty axes

[mhashad]

I got this error while running the LC command for energy range from 100MeV to 10000MeV however it works well for energy range from 100MeV to 500000MeV and it gives the result.dat file and the plots. Could you help me fix this problem.

Maybe there are no detections in that energy range so y is empty abd then the log fails, but it shouldn't spit that error. Let me have a look and maybe get a workaround ...

Ok, that is actually a strange error indeed. Can you provide a minimal example that produces it? I would like to do some tests.
