A very productive night of injector matching studies. I was able to take baseline scans with all 4 harps using the nominal beam with the current match in place. Given the match data in the main machine, we expect the emittance to be roughly 1.5x design in X and 2x in Y.
Taking scans with IHA0L07-10 yielded very different results across the harps. In particular, IHA0L09 and IHA0L10 give very odd results.
