It would be interesting to see Jamesburg's real pattern, both at C band, it's designed frequency, and then pushing it to higher frequencies, say, X band, and see how the pattern degrades, based on an RMS error which we determined to be in the vicinity of .050"
Hello Pat & EMErs.

Since this is VERY interesting theme (also for me), i would like to 
include some information about
RT32 radiotelescope - fine domestic antenna at Piwnice, near Torun.


Next link provides technical informations, as well as Observer's 
Handbook (!) unfortunately some
of the documents are in polish language or they are simply missing at 
the www site.
