Compare Gain/Sefd sep00 to aug02
nov,2002
The gain of the system improved between aug00
and nov02 because of:
-
the primary reflector adjustments (completed in sep01)
-
The lband wide, lband narrow, and cband receivers had their focus position
corrected (about lambda/2) in aug02,nov02.
The improvement
in gain/sefd are shown in the plots. The data was taken
using the heiles calibration scans. The gain values rely on the accuracy
of the cal values and the source fluxes. The SEFD relies only on the source
flux. The red line in each plot is the average value for the current values.
