Hi Eric, hi Tom,

Since we are not using the new electronics and the new trigger
channels at the FCDC, this never has been a problem for us, luckily
Tom has experience with it. We are currently in the process of
rewriting the read_fcdc_header/data/event functions, and I am
planning to make the different trigger types in the new CTF
dataformat explicitely available under the name of the channel. So
instead of a "backpanel trigger" and "frontpanel trigger", there will
be a "STIM" event, a  "UPPT001" event and similar events for all
trigger channels (i.e. based on the type code).
