Further Analysis of the Reconfiguration Memo by S. Guilloteau

Philosophy

Sensitivity is inversely proportional to the number of antennas (Na) and the square root of integration time. SG computes the "loss" per reconfiguration in terms of equivalent integration time needed to make up the lost sensitivity with the full configuration.

Time loss computed as a function of the number of antennas moved per day (original S. Guilloteau calculation). Surprisingly the number of transporters has little impact.

Time loss computed as a function of the number of antennas moved per day, but with an added constraint that at least 6 antennas are needed for post-move calibration.

Time loss computed as a function of the number of transporters (original ST calculation). Again, this dependence is relatively flat. The loss is larger if more antennas are move -- a result counter-intuitive, as SG states.

Time loss computed as a function of the number of transporters, but with the 6 antenna minimum calibration constraint. The impact of this added constraint is more visible here.

Time loss computed as a function of the number of transporters, same as above, but for the t_move = 3 hrs case (vs. 2 hrs above). The loss is larger as expected.

Time loss computed as a function of the number of transporters, same as above, but for the t_cal = 4 hrs case (vs. 2 hrs above). The loss scales up as expected.
