Did anyone else get that message from Paddy Leahy?
I've checked my junk filters and I didn't see it, and it's
not
in the fitswcs archive.  But turning to Mark's reply

I have to say that I find all of these Bxxxxxxx keywords to
be
completely in accord with FITS from its inception.  We may
be annoyed
by the 8-character keywords, but examples like this show
that we are
not limited by them.  I look forward to the refinement of
these
and the creation of some conventional values that get into
standards.
