You surprise me completely, that was not "flame-bait".

Original versions of G&C (it started as a single paper) used the CDi_j
variant of the CD00i00j matrix proposed by Hanisch & Wells (1988) which
came from the NASA-sponsored meeting held in Charlotesville in Jan/1988.
Isn't that where IRAF got the CD matrix?
However, we are obliged to you for convincing us to preserve CDELTn.
This followed a discussion between you and Eric at the AAS meeting in
Berkeley in 1993, I have the email from Eric detailing your reasons if
you want to see it. Consequently we reverted to CDELTi + matrix.
Initially we were going to call it CDi_j with the current meaning of
PCi_j but there were objections regarding prior conflicting usage in
IRAF so Eric changed the name. Your original email accepting this
solution is appended.

Later you insisted that we must revert to the CDi_j matrix. I don't
recall that you ever provided a reason, I believe it was simply because
it was the way IRAF did it. That is what we resisted, for the reasons
originally espoused by you in 1993, and for compelling reasons that
emerged subsequently, c.f. Sect. 2.1.2 of Paper I.

Point (4) in my itemised list refers to the AIPS convention, not the
WCS standard, so you've fundamentally misread what I was saying. Didn't
you adopt the AIPS convention in IRAF? If not, then I was mistaken.

Doesn't it use WCSLIB? Lindsay provided me with much valuable feedback
on the earlier versions of WCSLIB. I was given to understand that she
was modifying IRAF to use it. (Sadly, AIPS, Miriad and karma also have
not progressed beyond the AIPS convention and I'm sure there are many
more.)

All of the non-linear stuff came from Eric's original AIPS memos, my
aips++ memo, and what we added subsequently ourselves and with useful
input from a number of people. As far as I am aware, your input was
related to issues regarding the CD matrix. We were also vaguely aware
that you may have had something to do with alternate coordinate
descriptors but I have nothing to confirm that.
In fact, I did a meticulous search through thousands of emails (2880
would you believe! - see attached) to ensure that everyone who provided
significant input to the paper, not simply asking a question, is listed
in the acknowledgements. Stricty speaking, your input all relates to
Paper I. However, we included you in Paper II also as a courtesy.
Was there something else that I am unaware of?
Regards, Mark

Eric - this looks to me like it ought to resolve the problem. I will be
happy with whatever you choose to call the new matrix. My only comment is
that since most or all the other WCS keywords have a "C" prefix, it would be
more pleasing to call the new matrix C<something-other-than-D>. CD matrix
is "Coordinate Definition[Determination?] matrix" so logically one would be
looking for a word other than "Definition" and this would provide a name for
the new keyword. Perhaps "Coordinate Transformation matrix", CT? But as I
say, "PC" is fine with me if that is what you prefer. ("Politically Correct"
is certainly more fun than my suggestion though).
Cheers, Doug

Hi Eric,
The list is appended - this consists of all WCS email (2362 messages) plus
that of the fitswcs exploder (216); total 2578. It excludes my WCSLIB
(219) and PGSBOX (83) folders.
Including these, my grand total is - would you believe - 2880!
I've appended the script I wrote to count the senders. It assumes that
each message resides in a separate file (as in MH mail folders). It would
be interesting to see what figures you come up with. (If you use unix
mail you could just 'inc' it into MH for the purpose.)
I'll get back to you on the other question re. Paper I acknowledgements.
Cheers, Mark
