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)
    • test time for K-band tied-array phase tests at ATCA (Jamie, Richard)
  • Investigate/implement mixed mode correlation (64 MHz & 4 x 16 MHz) at Curtin correlator (Cormac, Chris) continuing
  • Need to train observers for all antennas as more remote observing is anticipated (Tasso) continuing
  • Investigate Rx for Methanol at ASKAP. Very desirable and usable. (Tasso)
  • CABB test version records no Tsys. Need to fix before LBA session. Consult with WEW.(Jamie)
  • Clock problems in Cd continuing. Need attention. (All)
  • Brazil e-VLBI (Tasso)
  • VPAK trnasfers. Sam Morrison till July 2012. Future? (Tasso)


  • For Mk5 observations at Parkes 2 people are not enough. Need more observers (GA, CASS)
  • Storage needs at antennas (ATNF)
  • Wiki logs from ASKAP (Chris)
  • Need RTFC to Tid (Chris, Shinji)
  • 32 GHz VLBI tests
    • Check for frequency offsets at ATCA. Talk to engineers. (Jamie)
    • 32 GHz radiator at ATCA?
    • Do Tid-Mp-ATCA tests
    • Do Mp-Tid pilot test?
  • Check Mk5b channels at Parkes and compare with Hart (Chris, Jonathan)
  • Tests on 16 TB Mk5 modules at UTas as issues at AuScope antennas (Jamie McCallum)
  • Radioastron support at Parkes for August 24? (Phil)
  • Test and commission new VSIC remote operation. (Chris)
    • Mp already done. Implement at Parkes.
  • Commission Cd L-band system (UTas)
  • Procure Xcube systems ? (CASS)


  • Organise next DiFX meeting in September 2012 (Chris). Participate (All)
  • Participation in Haystack e-VLBI workshop 22-24 October (All)

Next meeting: 16 August 2012
