FITS WCS papers I, II, and III are published.
FITS WCS paper IV lies in draft form.
FITS WCS paper V is in review now.
Jess Mink of Harvard/SAO/CfA and proposed an appendix for the text of the FITS WCS paper I (Representations of world coordinates in FITS). This proposal was not included into WCS paper I due to the late date of its origination. Nevertheless, we hope to rewrite it and submit it as an element of WCS paper IV.
The old document containing justifications for permitting WCS concatenation along with the text of the proposed appendix is available here as PostScript or PDF. We suppose that this might become known as "The WCSDEP Convention".
On a less formal level than the above, I propose that there should
be certain conventional values of the
My ruminations are here.
This is a quick overview of FITS keyword syntax and semantics at UCO/Lick Observatory. This includes keywords used by Keck instruments built at UCO/Lick.
This database is used to simplify the creation of user interfaces and to generate myriads of lines of source code for instrument control. It is also used as a notebook for defining the meaning of older keywords that have long been in use.
For more complete details on how these queries work, see Memes Demos, and Memes Overview.
The following links give several views of keywords which are found in the FITS files produced by various instruments which have been built by or inherited code from Lick.
The operation of instruments that are delivered to Keck Observatory is performed via keywords that query and modify states. Subsequent to HIRES these bundles of keywords have been stored in this relational database. As such, the database should contain the most comprehensive and authoritative information on the meaning of the keywords.
