Started the experiment with tied array of 2345 for both DAS, with reference antenna CA04 on W104.
Took the array to add CA01 back in after scan 182, at 04:09 UTC.
It took quite some time to fix a problem with an LO on CA01. We got back on source, with the tied array now 12345 for both DAS (same reference antenna), at 05:22:10 UTC.
