Here is a summary of the changes between last night and this morning.
ea25 was the reference antenna in both cases and for both IFs.

ea09 (rack1 slot3)  Both IFs changed by the same amount, -60 ns.

The delay in IF C changed in four antennas:
ea01 (rack1 slot1)  +60 ns
ea02 (rack1 slot2)  +60 ns
ea19 (rack1 slot0)  +50 ns
ea28 (rack2 slot1) +100 ns

It is interesting and surely a coincidence that all four antennas
in rack 1 are in these lists.  Michael rebooted at least one
station board this morning; unfortunately I cannot remember which
one.

Once we have some believable four pol'n product data in hand we
will see how well A and C are aligned.
