Guys,
This is a message Max sent to vlbiobs, but it bounced. Note that it means
the Huygens summary I sent out on Friday includes the wrong frequencies!!
I will send out an update later. The distributed vex schedule was correct
- Max's summary (and thus mine) were wrong.
Cheers
Chris

Not splitting hairs, but to be clear... There's no change IN THE SCHEDULE
FILES affecting HOBART between versions 2 and 3, at least I didn't expect
so. The frequencies in the schedule were and are as you've written below.
The mistake was my synopsis in the email.
And in both versions Hobart has a break in observing from 19:30 to 20:50.
If you record without break, then at most it's 7.75 hours (14:45-22:30)
=> 27900 sec * 512Mb/sec = 1743.75 GB (1.70 TB) (convention 1024MB=1GB,
etc). You should take the break.
