IVS Analysis Report for Q21270 ($21SEP27XK) 
       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: ISHIOKA did not observe due to EL motor trouble.
          NYALES20's data did not arrive at the correlator by the time of correlation, 
          but the correlator noted that no information about NYALES20's participation 
          in the session was available.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     3

Other comments: 

  The correlator provided the following station notes:

    ISHIOKA  (Is/Q): Station could not participate due to EL motor trouble.

    NYALE13S (Ns/w): Applied manual pcal.

    NYALES20 (Ny/N): No information available.

    SESHAN25 (Sh/C): RFI in S-band; three non-detections.

    WETTZELL (Wz/V): Ok.

  NYALE13S' station positions were estimated.
