IVS Analysis Report for Q18316 ($18NOV12XK) 
       This report is the official IVS analysis report that corresponds to 
       the database maintained by the IVS Data Centers for this session.  
   (Analyzed by Karen Baver, Goddard Space Flight Center VLBI Analysis Center.
    Spoolfile source: interactive solve/nuSolve analysis.) 

Problems: WETTZ13N observed with the wrong schedule.  
          After correlation, only two ISHIOKA-WETTZ13N and two NYALES20-WETTZ13N observations
          were usable, so those baselines had to be deselected.

          Eight WETTZ13N-WETTZELL were considered recoverable by the analysis software,
          but the correlator warned that only two observations would be usable and that the
          baseline should be ignored, so that baseline was also deselected.

          In another anomaly, 32 NYALES20-WETTZELL observations were used in the solution, 
          but the most recent available schedule at the CDDIS data center only had 31 scans.

          WETTZ13N's use of the wrong schedule introduced some "unscheduled" sources 
          (1546+027, 3C418, 1606+106, and 3C371), which has confused the scripts that 
          generate the analysis report template.  
     
          With so many problems, a truncated analysis report is being issued.
          This report might be expanded later, time permitting, or it might need
          to be corrected.

Number of observations rejected during correlation:   48 

    This includes:

       ISHIOKA :NYALES20, 0059+581, 07:41:43 --- not correlated in S-band 
       ISHIOKA :WETTZELL, 0059+581, 07:41:43 --- not correlated in S-band 
       WETTZ13N:WETTZELL, 1546+027, 07:03:31 --- not correlated in S-band 
       WETTZ13N:WETTZELL, 0716+714, 07:05:48 --- not correlated in S-band 
       WETTZ13N:WETTZELL, 1751+288, 07:37:28 --- not correlated in S-band 
       WETTZ13N:WETTZELL, 1606+106, 07:50:21 --- not correlated in S-band 

Number of observations not usable by the software:    32 


Number of observations rejected during analysis:      12 

    Only two ISHIOKA-WETTZ13N and two NYALES20-WETTZ13N observations were recoverable,
    so these observations had to be deselected.
    Eight WETTZ13N-WETTZELL observations were "recoverable", but the correlator warned that in
    reality, only two would be usable and that the baseline should be ignored.  
    So these eight observations were also deselected.

    The 12 deselected observations were:

    observation    2, ISHIOKA :WETTZ13N, 1849+670, 07:00:21, quality code X-band: 9 S-band: 9

Other comments:  The correlator reported that ISHIOKA had very low fringes
                 and pcal amplitude at UT 316-01741. 
    
                 The correlator also reported that the WETTZ13N baseline scans
                 had quality codes of 0 or N and that fringes were only found for
                 the scans at UT 316-0700 and UT 316-0743.
 
                 The correlator used WETTZELL as the clock reference station.
                 The analysis used ISHIOKA.
