|+||====== 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://www-ra.phys.utas.edu.au/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 ./readpower.sh script.|
|+||There were also multiple "formatter is offset from the FS time" and "warning onsource status is slewing" errors during this run.|
