Subject: options
Some food for thought:
If we are very uncertain about whether we can get a z~1.2 SN from this
search, we could put in a cancellation by 9 am PST tomorrow (Wednesday)
morning and recoup *all* 16 HST orbits. This is allowed because we
scheduled this SN with a slew option (which required special
permission).
If we do not cancel this Wednesday, but DO decide to cancel next
Wednesday (our nominal post-Keck deadline) because we don't have a
suitable SN, there would be to 10 orbits which we would have to use for
final references. Six of these would be in slightly non-optimal
filters (e.g. F775W rather than F814W). (This is not a terrible
alternative.)
If the Subaru observations go well tonight, then we do not need to
worry about excercising this option. Thus, it would be very useful if the
Subaru observers can let us know how the observations are progressing.
If the Subaru observers are not on-line, perhaps the CFHT observers can
check in on them, or at least report the Mauna Kea summit conditions
(through 2 am HST tonight - when the SDF is up).
