Other comments: 

  The correlator provided the following station notes:

     ISHIOKA  (Is/Q): Eight non-detections in X-band on baseline Is-Wn
                      (low SNR).

     NYALES20 (Ny/N): OK.

     WETTZ13N (Wn/W): Eight non-detections in X-band on baseline Is-Wn
                      (low SNR).
                      RFI in both bands on baseline Wn-Wz leading to one
                      G code in X-band; channel SR1U particularly affected
                      and removed from frine fitting.
                      Applied notch filters on baseline Wn-Wz.

     WETTZELL (Wz/V): RFI in both bands on baseline Wn-Wz leading to one
                      G code in X-band; channel SR1U particularly affected
                      and removed from frine fitting.
                      Applied notch filters on baseline Wn-Wz.
