Actions arising


  • Consolidation of the LBA Archive to include all ATNF + Swinburne + Curtin correlated LBA data. Should also add in eVLBI output data. Maintain complete archives at Curtin and ATNF (ATNF/Curtin)
    • ATNF to develop online access to this archive (ATNF) - Continuing
    • Arrange ATOA on-line access to archive (ATNF)
  • Copy LBA data archive from Curtin to ATNF (Curtin, Chris) continuing
  • Transfer of LBA archive from Curtin to ATNF needs route. Firewall issues? (Chris, Shaun)
  • Guidelines for phasing the atca more often during vlbi observations (ATNF) - to be revisited
  • Implement upgrade for programmable cable changes on VLBI DAS. (Chris, Jamie S) continuing
  • Contact Peter Mirtchin re DAS remote cabling changes via VSIC (Tasso)
  • Update Parkes VLBI notes on Wiki (Jamie, JER, Tasso)
    • Mk5 notes for Parkes on Wiki (Chris, JER, Tasso)
    • Parkes Calibration notes (JER, Ettore)
  • Investigate/implement mixed mode correlation (64 MHz & 4 x 16 MHz) at Curtin correlator (Cormac, Chris) continuing
  • Proposal for VLBI with GMRT for next round (All) continuing
  • Try automatic pcal via schedules on atca (Jamie S)
  • Need to train observers for all antennas as more remote observing is anticipated (Tasso) continuing
  • Organise e-VLBI demo with Brazil (Tasso)


  • Mixed-mode correlation is becoming critical issue for LBA. Needs to be brought up at DiFX meeting in December (Chris, Cormac, Tasso) done
  • LBA monitoring problems due to ares issues at UTas (Jamie M)
  • Ceduna issues persisting. (UTas)
    • Check station clock (Brett, Stas)
    • 1pps phase jumps. H-maser? Check with Russians (Brett)
    • Persistent phase jumps at all bands. Try test with Rb vs H-maser at S-band during lba session (Utas, CASS, Curtin)
  • Issues for next LBA session all completed
    • Mp back from 64MHz (Narrabri)
    • ASKAP ready at X-band. Need operations notes on Wiki (Tasso)
    • Liaise with Hart re schedules and rtfc (Chris, Cormac)
    • Prepare for rtfc with Mk5 at Ww and Hh (Chris, Cormac)
    • Prepare Ww for session (AUT)
  • eVLBI Demo to Hobart. (Ho, Ww, Mp) for 23/11/11. Postponed again
  • eVLBI demo to Korea at K-band (Chris)
  • Inputs to CASS changes to operations at Mopra and Parkes. Some on ATUC forum. LBA notes to be prepared. Deadine 30 Nov 11(Tasso) completed
  • Next LBA annual operations meeting in Marsfield. Best common week with no conflicts is 20-25 Feb 2012. Pick 2-3 days in the middle of that week. (Tasso)
