Session Notes for RD1301
Experiment notes by J. Gipson, NVI, Inc/NASA GSFC
The purpose of this session is to test mixed-mode observing.
Two of the stations--Gs and Wf--will be observing using a
broadband system. (Gs is the new 12M antenna at GGAO.) The
remaining stations will be using standard S-X equipment.
Haystack has successfully correlated broad-band observing
between Gs and Wf. In this session Haystack will see if they
can extract fringes between these stations and the normal S-X
stations.
The schedule was written by John Gipson.
The session will be correlated at Haystack.
If succesful this will be the first demonstration of mixed-mode
observing. In this sense this is a prototype for the kind of
observing we expect to do in the future as more and more
stations become broad-band. As we say in English--let's keep
our fingers crossed and hope for the best.
