   * "​Massive delay difference, clkoff was very high (order of e-01), mk5 was about 0.5s out of sync, but reported a sync error of 0. Counter and fmset didn't fix it so restarted the DBBC. That fixed the delay but then the field system crashed and had to be restarted."​ AUG025, 14/06/2016. **(Not a problem, was resolved.)**   * "​Massive delay difference, clkoff was very high (order of e-01), mk5 was about 0.5s out of sync, but reported a sync error of 0.

 +            - Jim's response "This may be an issue with the schedule being a little more optimistic on how much time is needed for pre-scan calibration (or similar), meaning recording always starts a little late. This is also a higher data rate experiment than our usual ones so you lose more data per unit time if things run late. I know that scheduling optimisation is something that Lucia, Davis et al have been working on for the AUG/AUA sessions. No doubt the logs will help them fine tune things some more."
