 +====== R1474 Observation ======
 +During the R1474 observations on the 16th March 2011 a problem was encountered. The autocorrelation plot looked like the one in the example that can usually be safely ignored see ([[http://​​auscope/​opswiki/​lib/​exe/​fetch.php?​w=500&​media=operations:​gv_dd1.pos-2.png|here]]). This was misinterpreted by the observer as an issue with the dbbc. Further investigation showed dimino to not be running. A restart of dimino did nothing to improve the situation. Furthermore there were then errors reported on pmstalmhb to do with being unable to contact the mk5.
 +The dbbc was re-setup at which time the autocorrelation display appeared normal. However observer error meant the wrong line number was given and the 12m went slewing off through a whole bunch of sources. The schedule was halted and resumed at the correct line number but now Mk5 connection issues re-emerged. A final restart of dimino fixed the issues.
 +After this systemp12 would no longer run, complaining about an error with the ./​ script.
 +There were also multiple "​formatter is offset from the FS time" and "​warning onsource status is slewing"​ errors during this run.
