Other comments: ISHIOKA did not observe.
The correlator report provided the following station notes:
ISHIOKA (Is/Q): Station didn't participate.
NYALES20 (Ny/N): Observed with warm receiver.
One non-detection in X-band on baseline Ny-Sh.
SESHAN25 (Sh/C): RFI in S-band; channel SR5U removed from
fringe-fitting.
A few non-detections in X-band.
One non-detection in S-band on baseline Sh-Wz.
WETTZ13N (Wn/W): RFI in S-band on baseline Wn-Wz causing two G codes.
WETTZELL (Wz/V): RFI in S-band on baseline Wn-Wz causing two G codes.
Three non-detections in X-band on baseline Sh-Wz.
One non-detection in S-band on the same baseline.
