====== R1657 **Ultra Rapid for Hobart 12m** ======

   * Ultra-Rapid set up procedure:
   * http://auscope.phys.utas.edu.au/opswiki/doku.php?id=operations:starting_monitoring_ureop
   * Also, check the schedule file:
   * http://auscope.phys.utas.edu.au/opswiki/doku.php?id=operations:documentation.ivs.drudg_ureop

**Ho** HOB+0102 Data recorded = 10624.396 GB

  * 16:54 UT - Unable to complete Ultra Rapid setup because write permissions to folder in Tsubuku are not granted. (VK)
  * 17:00 UT - Experiment started OK. NOTE: No autocorrelation plots because of Ultra Rapid. (VK)

**Ke** NTO-0007
 
  * 17:00 UT - Experiment started OK. (VK)

**Yg** BKG+0136
  * 17:00 UT - Power failure affected DBBC and counter gpibs. (VK)
  * 17:55 UT - First successful scan is 286-1755. Deficiency of 66 GB. (VK)
  * 18:10 UT - Commented out clkoff and maserdelay in midob using pfmed because of gpib errors
  * 18:31 UT - Update from Yg with gpib connector fixed. So halting schedule to restart fs to estab. comms.
  * 18:46 UT - Schedule restarted. Missed scans 286-1831 and 286-1837a. Total deficiency is ~75 GB

 Transfers of Yarragadee data completed on the 27th of October.

+STATION_NOTES

 HOBART12 (Hb/d): Ok.

 KATH12M  (Ke/a): Ok.

 YARRA12M (Yg/i): Late start at UT 286-1755, due to power failure.



Problems: Many problems!

 HOBART12 has at least 7 small clock breaks, but the software 
 cannot support them all. Breaks are set at 18:15 (+.73 nsec),
 06:25 (-.65 nsec), 09:00 (+1.31 nsec), 11:55 (-.52 nsec), and
 13:27 (-.58 nsec). And ~85 observations have to be deselected.

 ONSALA60 is very noisy and has many zero codes in X-band. The 
 log shows high X-band system temperatures.

 NYALES20's cable cal is bi-modal at times and has a large break
 (~84 nsec), similar to R1655. It is not applied, but this may
 produce some systematic errors since the cable and phase cal
 have an elevation dependence. 

 TSUKUB32 missed the first 7 hrs due to a typhoon.

 YARRA12M mised the first hour due to a power failure.

 FORTLEZA did not participate; problem with azimuth bearings.

 SESHAN25 did not participate; antenna motor problem.  


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.
