A new Resource Cost (RC) metric will be used in Cycle 22 and
beyond. The RC will be calculated for all non-TOO
targets. RC will replace "constraint categories" used in previous Cycles. Targets at high ecliptic latitude will incur significant RC even if they are not constrained.
TOO response categories have been updated. In addition, TOO follow-ups will count as half triggers for the purposes of counting triggers at the peer review.
There have been minor updates to the slew tax calculation.
The CXC has released an updated Cycle 22 Call for Proposals. A summary of changes is available.
