4. FITS WCS

BH: WCS proposals are good enough to publish - Griessen to move
forward BUT Calbretta has a new version which folk are not happy
with. 

Two weeks ago - NRAO want to see something move ahead - so bob will
work with eric and mark to find a way forward (PC vs CD matrix) - good
cooperation from eric+mark. 

s/w exists to support the two conventions.  relationship between PC
and CD is clear. They can coexist fully - this will satisfy all
communities.

reacting) - BH has gotten ( or will by Apr 15 )agreement from all
