[daip] (AIPS) question about the Y2K HUGE IMCLN image

[Samuel R Conner]

To Whom it may concern (I suspect Eric or Patrick),

   The Y2KHIMCLN image is a lovely X-Band image of Cygnus A, J2000 coordinates
and rotated 23 degrees counterclockwise.

   I would like to have a high resolution spectral index image of this source
between X and C bands --- I'm interested in what this source might look like if
observed at different frequencies (and it if notionally were more distant).
Chris Carilli has kindly provided me with a good C-band (B1950) image. REGRD
and OGEOM have given me excellent alignment of the two images.

   The reduction history of Y2KHIMCLN in its image header looks conventional and
I am wondering whether I can trust this image to have the right flux scale for
my spectral index (and, ultimately, observation simulation) purposes.

   Any advice?

 Thanks for your time and trouble,

Sincerely yours,

Sam Conner
