Constrained Observations
CXC
As in Cycle 7, the official limit is 15% of observations:
• Counting individual pointings
• Dividing long observations into orbit-sized chunks
• Counting TOO follow-ups
Cycle 7, peer-review approved constrained observations were
22% of the total due to teething problems in the GUI code
and the need to count some by hand. The CUC report has
been updated to include this information.

Grant Award Periods: as implemented for Cycle 7, all awards will
not be eligible for a 2 year period with a 1 year no-cost extension

Peer Review: Big Project Panel: an additional half day has been
added to the schedule for the BPP to allow more reading and
discussion time and reduce the stress level on all participants

larger percentage already. Are now in the final stages of inviting
reviewers.
