Rick took 2 sets of data, at L band, several sources over a 20x20 deg patch of sky. The first was from UT 18:30-1900, Jun 26; the other UT 01:22-01:50, Jun 27. Both datasets were taken with the CMP in good health (as far as I know) and both showed the large ~1m offsets for VLA antennas; while the EVLA was fine at the few-cm level. Vivek.
