Antennas 13, 14, and 18 gave good fringes on all IFs.
Antenna 16 is DEAD on IFs A and C. (This was also the case on the
preceding day).
Antenna 24 is DEAD on the LCP side (IFs C and D). This is the same
as at L-band. Also, the reported Tsys are nonsensical on these IFs,
while they are fine on the RCP side.
Antenna 26 is not outfitted at C-band yet.
Sensitivity: With a single exception (14C), the EVLA antennas are
at the top of the sensitivity rankings. The named antenna-IF (14C) is
the worst in the array. I have no idea why -- the reported Tsys is
fine. Stability is good. Bandpass is normal.
