    observation   27, ISHIOKA :WETTZELL, 1726+455, 08:22:24, quality code X-band: 0 S-band: 9 

Number of observations rejected during analysis:       1 

    observation    9, ISHIOKA :WETTZELL, 0016+731, 07:45:48, which fits at     3572.3 +/-      66.0 ps 

Other comments:

The correlator report's correlator notes said:

 The fringe amplitude of X-band were weak. The observed SNRs were only
 about 50 % of the predicted SNRs.

 Scan 012-0821: FQ = 0 on X-band, source 1726+455
 There was good integration time but low SNR.

The correlator report's station notes said:

 ISHIOKA (I-Is): The pcal amplitude of the X-band were weak than usual.
                  observed pcal amplitude : about 2 %
                     usual pcal amplitude : about 3 %

 WETTZELL(V-Wz): The pcal amplitude of the X-band were weak than usual.
                  observed pcal amplitude : about 4 %
                     usual pcal amplitude : about 5 %

Parameterization:

     atmosphere offset for:
         ISHIOKA WETTZELL
     clock offset, first order term, and second order term for:
         WETTZELL

Clock breaks: None
