Hb

• (20:36 UT, Lucia): Large clock drifts (delay differences) from the beginning. After several DBBC config/reboots, looks stable now. First good scan# 303-2028 @303/20:28
• recording to module HOB+0105. 0 GB.
• strong RFI in last two s-band channels
• Deficit of ~120 GB due to late start (vk)
• 304/02:28 UT - Delay difference has been drifting since around 01:30 UT. JMc says to keep an eye on it until it drops below -0.300 msec.
• 03:19 UT - Halting schedule to reconfigure DBBC as delay difference has hit -0.330 msec.
• 03:30 UT - Restarted missed scan: 304-0324
• 04:00 UT - Halting schedule to reconfigure DBBC as delay difference is drifting.
• 04:08 UT - Restarted. Missed scans: 304-0353,304-0407a

Ke

• recording to module USN-0033. 0 GB
• two dodgy chanels in DBBC and high Tsys. This is a known problem.
• setup: couldn't snychronise times; restart DBBC

Yg

• (20:27 UT, Lucia): persistent ERROR 2014.303.20:28:37.16?ERROR s5 -104 rfpcn: time-out, connection closed
• (20:27 UT, Lucia): lost antenna control due to power failure. Lost scans between 19:29 and 19:48 UT (scan# 303-1940 and 303-1945)
• recording to module USN-0178. 0 GB
• troubles with Internet Connection to Yg while setting up (could not even ssh to). Yg people fixed that by rebooting the router (?).
• More internet problems at about 09:09 UT lost connection and did not get it back until 10:21UT (could have been a lot sooner if I hadn't been holding out false hope that it might fix itself), guys rebooted the D-link

error for fringe check: not successful. Automatically selected source was not visible from Yg (antenna limits reached).

HOBART12 (Hb/H): Station experienced large clock drifts from start

               of session to 303-2028.

               Clock again drifted after approximately 303-0130, 
               continuing until DBBC reset at 304-0407.

               Low fringe amplitudes in channel SR6U, 
               leading to occasional 'G' codes.

               Channel SR6U removed from fringe fitting.

KATH12M (Ke/A): Ok. YARRA12M (Yg/Y): Ok.

Other comments: a clock break in clock rates reported by the correlator for HOBART12. The effect is visible only for the single band delays, no additional break were added to the station. A small clock break is on YARRA12M baselines at the X-band.

• Recoverable: can be included in the solution.
• * Total includes distinct observations only.

MISSED:    Station was scheduled, but it did not observe.
NOT CORR:  Station was scheduled but not correlated.
NOT USED:  Usable data was generated for this station,
           but the analyst rejected it all.
