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
  • 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)
  • 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
  • Follow-up of zoom-modes for VLBI on atca (Jamie, Tasso) Continuing
  • Feed-back on tied-array operation (correlator)
  • Report on possible persistent frequency problem at Cd (correlator)
  • Plan for VLBI demos with AuScope antennas (UTas)


  • Ww issues at X-band such as pointing to be addressed (AUT)
  • Get AuScope fix for Elevation encoder drift to NZ and Parkes (Jim)
  • Try automatic pcal via schedules on atca (Jamie S)
  • Complete ASKAP data transfers from June observations (Chris, Cormac)
  • Fringe tests for Cd at 25 GHz (Chris, Jamie M)
  • Updated Cdisko2 at Ho and Cd (Chris, Jamie M)
  • Check mixed-mode correlation issues with Adam while he is at Curtin. Ascertain extent (Cormac)
  • Investigate sideband separation at atca (week fringes seen on inversion) (Chris, Cormac, Jamie)
  • Transfer of MK5 data from Parkes from last session (Chris)
  • Mk5 disks (2 TB+) to Tid for next session (Chris)
  • Distribute LBA schedules by Monday evening. Hart to be notified (Cormac)
  • Need to train observers for all antennas as more remote observing is anticipated (Tasso)
  • Arrange observers for 12-15 August session (Chris is unavailable) (Tasso)
  • Transfer of LBA archive from Curtin to ATNF needs route. Firewall issues? (Chris, Shaun)
  • Contact Peter Mirtchin re DAS remote cabling changes via VSIC (Tasso)

Next meeting: Wedn 07 September 2011, 14:00 AEST (04 UT)
