[fitsbits] start of Public Comment Period on the INHERIT convention

[Frank Valdes]

I will respond with the DECam raw data from the telescope.  This is a good question for this discussion.  If this goes somewhere interesting I can look at the other NOAO mosaic cameras and the calibrated files.

The keywords from the list at http://heasarc.gsfc.nasa.gov/docs/fcg/standard_dict.html that are inherited are:

DATE-OBS, INSTRUME, OBJECT, OBSERVER, TELESCOP

I might also mention a couple that are important but not on the list:

EXPTIME, FILTER, RA, DEC

There are no WCS keywords even from the advanced WCS papers or the TPV convention used by DECam.
