COMMENTS

The SNR was low for scan at source 2234+282 on X-band, and the fringe was also.
Analyzed results of 045/0740 and 045/0758 were a little larger in residual plot,
but not suppressed.
False peak was likely to be detected on some channel.

 TSUKUB32(T-Ts): All scans were processed with 8 or 9 quality codes.

 Wettzell(V-Wz): All scans were processed with 8 or 9 quality codes.
                 Error rate level of recorder head C was higher during
                 playback.
