@ihrivnac the doxymodules.h files are actually required, no?

@vkucera I am pretty convinced the doxymodules.h are needed.

@vkucera I am pretty convinced the doxymodules.h are needed.

Are you sure? There are only 3 of them in the entire repo.

Hi @vkucera
Thanks for this cleanup of the EMCal code! (And sorry for my late response)
I am not sure about the doxymodules. This is something Markus did, and I don't know exactly how they work.
I actually did not realize that the test for the badChannelScale factors is not used in the test. Could you leave it in, and I will properly implement it in the tests?
