Here's what Chandra uses, in accordance with HEASARC convention:

MISSION = 'AXAF ' / Project
TELESCOP= 'CHANDRA ' / Telescope
INSTRUME= 'HRC ' / Instrument
GRATING = 'LETG ' / Grating
DETNAM = 'HRC-S ' / Detector
OBS_MODE= 'POINTING' / Observation mode
DATAMODE= 'OBSERVING' / Data mode

In a sense, MISSION is equivalent to OBSERVAT.

I was reviewing a document suggesting keywords to be used in FITS headers, and I
was wondering if there was any kind of defacto standard beyond that in the FITS
definition. The keywords being suggested were as follows

INSTRUME FITS Standard
TELESCOP FITS Standard

DETECTOR The detector used
INSTITUT The institution
OBSERVAT The observatory
NETWORK I think this keyword is meant to be used for data taken by a
network of observatories, such as the GONG network.

Except for the first two, which are standard FITS keywords, are any of the other
keywords used elsewhere? Or are their other forms which capture the same concepts?

Thank you,

William Thompson
