I looked at a couple times when power into the IMC was increased, and the power change shows up on sensors, specifically IO GigE 2 (IMC_IN), IMC-WFS_A_DC_PIT, and IM4_TRANS_YAW. The IMC mirror alignment and PZT also respond.  Plots attached are 1) power to 10W, 2) power to 27W, both with sensors, and 3) power to 27W showing IMC mirror alignment.
