Add interaction channel for particles

[YouSchnabel]

In neutrino physics, the interaction channel for a particle is used to distinguish between data sets (muon neutrino charged-current interactions resulting in muons are "track" data sets, all others are "shower" data sets). Should be able to distinguish between these.

Do you mean that, for a neutrino data release, some datasets will contain only "track" events and some only "shower" events? To rephrase the question, will one entry of ObsCore (ie one event-list) being characterised by only "track" events and some only "shower" events?

If yes, are you proposing to add a collumn into the HE ObsCore extension? If yes, can you write the corresponding sub-section in the section 3?
