[GMVAtech 67] Re: 7mm add on

[Uwe Bach]

Hi,

so far Effelsberg can do this only with changing between prime and secondary focus, which takes roughly 30min. It would require a gap of 45 min between different schedules and, I would say, at least a 4 hour long schedule at each frequency. Otherwise we lose too much time for focus changes.

Cheers,
Uwe
