Notes. Overview of the time spent in calibration function blocks for various datasets (daytime and nighttime). We measured the overall time (flagging, calibrating, imaging) of an ACM to be 250 ms (σ = 15 ms) for nighttime data and 1700 ms (σ = 100 ms) for daytime data using current generation hardware and calibrating to convergence. The day latency is seen to be much worse due to the presence of a very active Sun leading to significant modeling errors.
