Epoch question & UCAC2
David Oesper Feb 5, 2012
Kudos, Bill, on the new Guide 9.0! I have just two questions:
(1) Could someone explain to me the difference between the "mean of date" epoch and "apparent" epoch (Settings...Formats...Epoch:)?
(2) How do I get the UCAC2 numbers to show up? IOTA is not yet using UCAC3 for asteroid occultation predictions, but is still using UCAC2. Also, regarding UCAC2, I have often seen star designations written as 2UCAC. I'm assuming these are identically equal to the UCAC2 values.
