Normally I don't fall for the flame-bait, but actually
significant
parts of the WCS concept and technology were developed
independently
in IRAF, way back in the eighties, and with great reluctance
were
later allowed to influence the development of the actual WCS
standard,
which has always been tightly controlled by G&C.  We
didn't merely
"adopt" it later as you suggest above - the
current WCS implementation
in IRAF predates the WCS standard.  In the end we did not
mind since
it turned out ok - plus it could never have been as good as
it is
without the expertise of all involved.  But please don't
suggest that
WCS came only from the radio/AIPS community.
