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

[ktf]

@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?

@ktf @ihrivnac Does someone know what the doxymodules.h files are for?
From the name I assume it is something related to the Doxygen documentation but then it seems suspicious to me that there are only 3 of them, while I would expect them to appear in other directories too, at least for the other detectors.

I vaguely remember they are for customising the various section contents? Maybe only EMCAL ever bothered having something different from the default? @ihrivnac do you remember?

[vkucera]

@jokonig I have removed testBadChannelScaleFactors.cxx and the doxymodules.h files from the PR.
