Hb TR-00014

RFI spikes in ch 14, 15 (0-15) (Liza)
22:07 UT - Windstowed (vk)
22:46 UT - Observations resumed. Missed scans: 300-2210b to 300-2241 corresponding to deficit of 36 Gb
23:19 UT - Windstowed
23:31 UT - Obs resumed. Missed scans: 300-2320a, 300-2325b and 300-2327 corresponding to cumulative deficit of 42 Gb
Hb needed manual intervention to recover from above windstows.
301/00:43 UT - Windstowed
00:52 UT - Obs resumed. Missed scans: 301-0040, 301-0046 and 301-0050 corresponding to cumulative deficit of 62 Gb.
Reported cumulative deficit with disk_pos is ~20 Gb, not 62 Gb. This is because mk5 begins to record after command to exit windstow is issued, even though the antenna drives do not activate until fs is restarted.
01:24 UT - Windstowd
07:12 UT - Returned from windstow. First scan 301-0712a. (DH)

Experiment started OK by Dave (vk)
Steep slopes on chans 11 & 12 in autocorrelation plot
301/01:54 UT - disk_pos is 40 GB in excess?

HOBART12 (Hb/d): Missed scans:

                from UT 300-2210b to UT 300-2241, 
                at UT 300-2320a, UT 300-2325b and UT 300-2327,
                at UT 301-0040, UT 301-0046 and UT 301-0050, 
                from UT 301-0124 to UT 301-0712
                due to windstow.

                Note that some of the above scans contribute to the 
                statistics as non-detections.

KATH12M (Ke/a): Ok.

YARRA12M (Yg/i): Ok.

Problems: Hobart12 had several windstows, one lasting ~6 hrs.

        The cable cal at NYALES20 was unstable, with 2 breaks.
        It was not applied. This has happened several times
        recently and is being investigated.

Parameterization comments: None.

Other comments: None.

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.
