J. Kissel, J. Warner WP 11821 ECR E2200226 IIET 12161 As Jim and others are starting to build up a good MEDM interface and otherwise use the rest of the HAM1 TT L4C feed-forward infrastructure I installed several moons ago (see 63115 and 63300), we've discovered that I overlooked adding useful test points at the summation point of the DC centering DOFS DC1 and DC2. These "FFHAM1_IN" and "FFTRGT_IN" fast test points, and corresponding EPICs readbacks were added to all the other summation points (CHARD, PRC1, REFLWFS_RF9_I, etc.), I just missed it for the DC centering loops. Attached are screenshots after they're now in place. We'll install these by recompiling, installing, and restarting the h1asc.mdl front-end model tomorrrow during maintenance.
