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
    • Try automatic pcal via schedules on atca (Jamie S)
  • 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
  • Need to train observers for all antennas as more remote observing is anticipated (Tasso) continuing

  • Check with NZ re issues with Ww drivs (Tasso)
  • Implement larger filesizes for recording (1 minute) since number of files is impacting the PB store (Chris, Jamie)
  • Need correlator report on telescope performances before March session (Curtin)
  • Need ASKAP data from Nov session. Disk needs to be sent to MRO and data copied (Tasso, Chris)
  • Investigate Rx for Methanol at ASKAP. Very desirable and usable. (Tasso)
  • Check and delete old VTxxx data at Mp and At (Chris)
  • Check if UTas has full 10G connection to campus (Simon)
  • Progress GMRT vlbi tests (ATNF, Curtin)
