What drives the requirement for background loop stabilization within 20 seconds?
A. The value of 20 seconds has been flown down from the overall timeline for acquiring a science target. Offloading low-order modes to the telescope and obtaining TWFS measurements with very dim guide stars may be the most challenging tasks to complete in 20 seconds. Most other computations of gains, filters, and weights should be nearing convergence after 2 updates at a rate of 0.1 Hz.
