Two Voyager questions Paolo Ulivi 10-19-2006

 While researching for my book on solar system exploration two questions
have surfaced:
1) In some articles the vidicon sensor of Voyager 2 was said to be 50
per cent more sensitive than that of its sister. Was it just by chance
or were the better sensors actually mounted on the probe flying the JSUN
trajectory?
2) At the time of the Neptune flyby the Goldstone DSN antenna was
arrayed with the Very Large Array, Canberra was pooled with Usuda in
Japan. Why wasn't Madrid arrayed with, for example, the Effelsberg
radiotelescope in Germany? Was it because Neptune would be very low in
the German sky at the time of encounter?
thanks for replies
Paolo

I was interested to see that you considerably more success with this
question on the Unmanned Spaceflight forum at

I feel that doesn't bode well for the future of the newsgroups.

Nope. Despite all the false alarms about the death of Usenet, I think
that webfora and blogs are going to do it in.
