Other comments: 

  The correlator provided the following station notes:

    +STATION_NOTES

       ISHIOKA  (Is/Q): One non-detection in X-band on Is-Ny baseline.

       NYALES20 (Ny/N): One non-detection in X-band on Is-Ny baseline.

       SESHAN25 (Sh/C): Low fringe amplitude in channel XR8L leading to several
                        G codes; channel removed from fringe fitting.

       WETTZELL (Wz/V): Ok.
