Ant 18 at X-band - as in my earlier message.
The other antennas were pretty good overall, but
there were a couple of exceptions and oddities as noted below.
Antenna 13:
1. Fringes at all bands, L,C,X,K,Q, all IF's.
2. There is a 10-sec sawtooth in the phase (all IF's), of
magnitude 3degrees per GHz, i.e. <5deg or absent at L-band,
120 degrees at Q-band.
3. At Q-band there were fringes on the AC pair, for 4 scans
spread over 1.5 hours; but no fringes on any scan on BD.
Antennas 14, 16 were healthy at L,C,X,K, bands.
However, at Q-band, there were fringes on AC and BD on ant 14,
but ant 16 had no fringes for 3 of the 4 scans on the BD side.
Vivek.
