Proposed appendix for FITS WCS Paper IV
FITS WCS papers I and II are published.
FITS WCS paper III is nearing completion and needs
YOU to review it.
FITS WCS paper IV is in draft form.
They are visible at the websites of
Eric Greisen and
Doug 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 intend 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
We suspect that this will become known as ``The WCSDEP Convention''.
Proposed conventional values for
On a less formal level than the above, I propose that there should be
certain conventional values of the
keywords. My ruminations are here.
Issues not addressed by WCS Papers I, II, and III (and IV)
I ruminate informally about things that are
not (and cannot be) addressed by the current drafts of the WCS papers.
FITS Keywords peculiar to UCO/Lick Observatory
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.
Live Database of UCO/Lick (and Keck) FITS keywords
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
and Memes Overview.
Bundles of FITS keywords
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.
Bundles of KTL keywords
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.
An admission that we didn't always get things right from the start.
Motivated by the DEIMOS
instrument which has a detector consisting of 8 CCDs whose pixels will
be read simultaneously into a single FITS file.
