AuScope (Hobart, Katherine and Yarragadee)
Nothing new to report since August.
Jim Lovell - 22 Sep 2016
Testing of the prototype Callisto feed was completed on the Hobart 12m in August, finishing with a successful fringe test with Ishioka and Kashima. A report on the Australia-Japan broadband fringe tests is available. The receiver operated reliably and stably throughout, installation and operating procedures went smoothly. We are continuing to work on optimising the antenna optics. Still on track for a January arrival of the production systems.

Prototype testing on Callisto feed/receiver system at Hobart due for completion in mid August. The system is performing well but some issues with the 12m optics need addressing: subreflector optimization has helped but more work is required.

Dynamic Observing
We are undertaking a series of Dynamic Observing test observations with the AuScope array and any other antennas that wish to join. Observations are done is S/X mode, 16 x 16 MHz IFs with 2-bit sampling (1 Gbps). The main aims are to test real-time scheduling and observing techniques and make data comparisons between traditional observing modes and dynamic observing output. Data are being eTransferred to and correlated in Vienna. Schedules are updated on a 15-min cycle and telescopes maintain control over participation. For more information, see the Dynamic Observing page on the AuScope VLBI wiki.
Observing program for 2016:
| Experiment | Start (at 0 UT) | Duration (h) | Antennas | Comments |
|---|---|---|---|---|
| ds239 | Aug 27 | 48 | HbKeYg | Successful uninterrupted 72h on all antennas |
| ds258 | Sep 14 | 24 | HbKeYg | Scheduler adapted well to antenna drop-outs |
| Oct 1 | 48 | HbKeYgHt | Hart15 to join | |
| Oct 15 | 48 | HbKeYg+ | ||
| Oct 26 | 24 | HbKeYg+ | ||
| Nov 12 | 48 | HbKeYg+ | ||
