A Proposal for a TIMESYS Element in VOTable

[Tom McGlynn]

It seems to me that this makes no accommodation for satellites where the 
reference position is variable but not
unknown.  The definition of topocentric is according to my dictionary: 
"**relating to, measured from, or as if observed from a particular point 
on the earth's surface *: *having or relating to such a point as origin" 
so TOPOCENTER is fine for earth based observations (though there are 
balloons that move quite a bit during an observation campaign) but it 
would be a stretch to use it for satellites.  I wouldn't want to say 
UNKNOWN though.    Maybe SATELLITE or VARIABLE? Lots of HEASARC data 
have times that are measured at the satellite -- and that includes lots 
of the GRB detecting satellites for which this kind of feature would be 
very nice.
