This morning I turned on HEPI feedforward to BSC St1 on all of the BSC's. I took measurement as I went, generally improvements between 5x and 10x, between 1 and ~10 hz. The attached plot from ITMY is one of the better ones, but typical. Green is the ground, black is before, red is after. I still have to get some time to bring down FF to get some gain matching measurements, but I can probably fit this in on some morning before the commissioners come in.
