NASA Analysis Report for Q18077 ($18MAR18XK) 
       This report is a contributed analysis report that does not correspond 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: None. 

Number of observations rejected during correlation:  25 

   The ISHIOKA-KASHIM34 baseline was not correlated because it is too short to provide a good UT1 estimation.

Number of observations not usable by the software:     0 

Number of observations rejected during analysis:       0 

Other comments: WETTZELL was scheduled, but WETTZ13N replaced it
                because of equipment problems at WETTZELL.

Parameterization: 
   10 parameters: 
     UT1 offset 
     atmosphere offset for:
         ISHIOKA KASHIM34 WETTZ13N
     clock offset, first order term, and second order term for:
         KASHIM34 WETTZ13N

Clock breaks: None
