 +At UT13:40 day 241, the delay difference at Katherine started to drift quite badly, had to run fmset at 13.53UT (Imogen)
  
 +For some reason, gnuplot will not plot values of ke_ddif.txt past ~11:00UT - not sure why (Imogen).

 +At 14:29UT, restarted DBBC as clock drift was still occurring, ran fmset to resync dbbc and mark5. ​ Delay seems to be stable as of 14:42UT
