2003 LBA Ops meeting

Tasso Tzioumis

Previous LBA ops meeting

• 3 April 2003, Hobart

• Minutes on www.atnf.csiro.au/vlbi/reports/

• 19 Action Items!

• Quick review

• Keep in mind during this meeting.

? 1) Investigate whether a sufficiently sensitive broadband system (either 4-7 GHz or 6-8 GHz) can be constructed for Ceduna [Action Peter McCulloch]

X 2) Make Mopra controllable from the PCFS [Action Chris Phillips]

X 3) Commisioning of XY phase measurement system at Mopra [Action John Reynolds, Warwick Wilson]

X 4) Reduction of difference in cable lengths at Mopra [Action Tasso Tzioumis]

X 5) Modifications to CACAL/CATIE to reduce improve phase tracking at 22 GHz [Action Tasso Tzioumis, John Reynolds]

X 6) Attempt a 3mm VLBI test experiment Narrabri-Mopra once final 3mm systems installed at each location. [Action Tasso Tzioumis]

+? 7) HP synthesiser currently at Ceduna, to be returned to Parkes [Action Simon Ellingsen]

+ 8) Determine who is maintaining the Parkes maser, last serviced by NML in 1998 [Action John Reynolds]

X 9) ATCA pipeline to provide online total flux measurement, plus a flag for

bad fit (similar to work required for VO) [Action Dave McConnell]

X? 10) Gain curves need to be produced for all antennas, particularly at

higher frequencies. Email these to Roopesh for inclusion on LBA web site [Action John Reynolds, Simon Ellingsen, Jim Lovell, Tasso Tzioumis]

? 11) Produce a checklist for observers containing a list of information that should be entered into the PCFS log [Action Roopesh Ojha]

+ 12) Produce a small number of example key files for scheduling LBA experiments with Craig Walkers SCHED program [Action Chris Phillips]

+? 13) Chris Phillips requires the frequency range for each of our receivers so that the information can be included in the SCHED databases

[Action Brett Reid, John Reynolds]

+ 14) Investigate if its possible to make SCHED produce snap files with tape changes on the hour and how to get frequency information written into the .sum files

[Action Tasso Tzioumis, Chris Phillips]

+ 15) It is desirable to produce a nice web version of the VLBI schedule such as is done for the ATCA. Dave McConnell will give a copy of his Java program used for the ATCA schedules to John & Jim. [Action Dave McConnell]

+? 16) The correlator manual needs updating [Action Tasso Tzioumis]

? 17) We need better integration of the tape, proposal and correlator databases

[Action Tasso Tzioumis, Jim Lovell]

+ 18) ATUC has requested notification to users who's proposals will expire. A list of project which expire during the next term needs to be produced prior to each TAC meeting [Action John Reynolds, Jim Lovell]

X 19) AIPS++ is looking for specific science programs to support, we should put forward a list of VLBI requirements [Action Dave McConnell]
