In April 2004, again we revisited Ganymede with SHARCII.  Here are the before and after pictures.
Off:  FWHM=10.4 arc sec, peak=64.6 Jy/Beam, total flux=62.1 Jy
On:  FWHM=8.8 arc sec, peak=129 Jy/Beam, total flux=88 Jy
FWHM improvement of 18%    Peak improvement of 50%    Total Flux improvement of 40%
ZA = 11 to 15¡   Perspective alt 10 az 90
Thoughout this run, the DSOS improved the signal power between 40 to 45%
