Other comments: WETTZ13N could not find the schedule posted to IVS.  So this station
                could not observe.

Parameterization: 
   6 parameters: 
     UT1 offset 
     atmosphere offset for:
         MK-VLBA PIETOWN
     clock offset, first order term, and second order term for:
         PIETOWN

Clock breaks: None
