Other comments: Due to the recent problems with the WETTZELL cable cal data,
                a note is being made here that the cable calibration correction
                was used for this session and slightly improved the session fit 
                and the UT1 formal error.  In this session, the values ranged
                from ~ -20 ps to ~ 25 ps.

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
