Other comments: The session has been re-correlated and re-analyzed to add the MK-VLBA weather and cable data,
                which were originally unavailable.

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

Clock breaks: None
