[iaufwg] FITS conventions

[Francois Ochsenbein]

Dear Mark,

Thanks for the "Colour FITS" paper -- quite interesting despite I coulnd't
get the colouts on Fig.1, and Eqs. 8-10 seem to be missing.
It is certainly important to define accurately the colours in FITS,
in a device-independent manner. My fear is that this could require another
decade until the final agreement... for a recommendation about the contents of
the CTYPEx keywords. BTW I was not aware of the 'sRGB', 'CIELUV' or 'CIELAB' 
conventions, they would most likely be worth being publised in the FITS
convention pages  (http://fits.gsfc.nasa.gov/fits_conventions.html)

About using other packages -- it is serious to propose using tiff or
GeoTIFF ? Should we seriously think about moving away from FITS because
other formats have reached a similar maturity as FITS ? A fundamental
question for the future !
