Other comments: 

  The correlator report provided the following correlator section notes:

   Scan 100-0730: FQ = 0 on X/S-band, source 1606+106  
     Scan 100-0736: FQ = 0 on X/S-band, source 1849+670  
     Scan 100-0758: FQ = 0 on X/S-band, source 1746+470  
     Scan 100-0824: FQ = 0 on X/S-band, source 1806+456  
     There were good integration time but low SNR.

     Scan 100-0809: FQ = 0 on X-band, source 1053+704  
     There was 50% or less of assumption file sizes.

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
