STScI also routinely uses TELESCOP ("HST", and eventually "JWST"?),
INSTRUME ("ACS,COS,FGS,FOC,FOS,GHRS,HSP,NICMOS,STIS,WFPC2,WFC3"),
as well as DETECTOR (most HST instruments have more than one detector
channel in them). We don't use INSTITUT or OBSERVAT. As with the NOAO
usage, a lot of our software uses the INSTRUME and DETECTOR keywords.
