NOTE 1: The W and ETA reported  here were determined from deconvolving
one dimensional scans of Ta* across planet disks.   A non-linear,
least square, two parameter fit for beam size, W, and beam coupling
efficiency, ETA, was used. The antenna beam was assumed to have a
circularly symmetric gaussian profile. The coupling efficency, ETA,
reported here is a product of the cold spill over efficency and the
main beam efficency.   Because of the assumption of circular symmetry,
the ETA, reported for the AZ, and EL axii will be different values if
the beam was elliptical (i.e. 650 beam). 

Note2: W = is the radius (arc seconds) to the 1/e**2 pwr point (-8.7db).

       FWHM = 1.177*W

Note3: Secondary edge tapers reported  by Jacob based on direct measurements.
