VEP_UCD for relating to an high energy event

[loumir]

We added various suggestions for dealing with an event related quantity:

1. instr.event
   but event does not belong to the instrument , it is rather an observed 'phenomenon' , so obs.event would do

S obs.event Related to a signal messenger detection (photon or particle)

thanks for improving the definition if needed ..

Then from this term , we can set UCDs for all measured quantities and labels for an event.

event grade : as meta.code.class;obs.event. ( defined from a detector pixel island, for instance)
event identifier : as meta.id;obs.event
event type: as meta.code.class;obs.event (defined according to some decision in the analysis pipeline)

this proposal has been changed in the Semantics WG revision , and replaced by instr.detection instead . The same UCD combinations for the grade and type of an event can be applied .

I argue that instr.detection is at least equally as bad as (if not worse than) instr.event from the perspective that the term "detection" is very widely used in astronomy, and perhaps even more widely used than than the term "event". Using "detection" in this manner is almost certainly going to be more confusing to the average astronomer than using the term "event" (and I think the latter is already too overloaded). At least the community generally recognizes "event-list" (and the use of "event") in association with HEA; a list of "detections" would have a totally different meaning.
