Actions arising


  • LBA data archive consolidation and copy at CASS. (CASS, Curtin)
    • LBA data archive. Need ATNF disk space (Tasso, Shaun) Continuing
  • ATCA phasing. Check performance and implementation (Jamie S, Richard) Updated
    • Definitely need >200 mJy calibrators. Stress in documentation. (ATNF)
    • Recommend strong calibrators » 200 Mjy ~every hour (depends on weather) + possible weaker calibrators more often (ATNF)
    • Ask PIs to nominate phase-cals and check fluxes BEFORE scheduled observations (Phil, Jasmie S)
  • ATCA Tsys via CABB (CASS) Updated
    • Investigate implementation by Bob Sault (Tasso)
    • Consult with Carrad and Sault about Tsys implementation on the CABB (Tasso)
    • Check with WEW and test whether acal scale preserved when mode changed to VLBI (Jamie S)
  • Observer training and remote observing (Tasso) Continuing
  • Wiki logs (All) Continuing
    • Log transfers quickly to FTP area and/or Wiki (ALL) Continuing
    • Annual “best” wiki-log competition. To be judged by correlator at annual Ops meeting. (Cormac)
  • Schedule more 32 GHz tests with ATCA? (Phil) Continuing
  • Pawsey centre access for VLBI and eVLBI (Chris, Cormac) Continuing
  • Linear to Circular polarisation conversion. (Chris, Richard, Cormac) Continuing
  • Monitoring “check-list” for ATNF telescopes (Chris, Jamie S) Continuing
  • Monica implementation at Ceduna (Jamie & Jamie) Done
  • Remote access to Ceduna VNC via Hobart? (Tasso, Jamie M.) Done
    • VNC within VNC ? (Jamie M, Tasso)
  • Remote access to Ww (Stuart, Tasso) Done
  • Simon Ellingsen complex schedules. Send frequency changes list to Ettore (Parkes) and Quick (Hart) for development of LO setups (Simon, Chris) Done
    • Rationalise Simon's schedules (Cormac, Simon, Chris)
  • DASPRO for Parkes needs updating to reflect Mars Rx changes (Chris) Done
  • Check-list for ASKAP Rx changes. Especially 100 MHz reference for X-band. (Tasso, Suzy). Continuing
    • Include on Wiki documentation (Tasso)
  • RTFC needs >0.5 hours for Mk5 and complex (e.g Simon's) setups (Phil) Done
  • Eliminate separate rtfc schedules except for special modes (Cormac) Done
    • include in main schedules for 1st hour
    • Inform PIs of suitable fringe-finders from block-schedule (Cormac, Chris)
    • List of 22 GHz calibrators for Hart (Chris)
    • Ask Roopesh for calibrator update at 8 and 22 GHz (Chris)
  • For ATCA include in Wiki log: ref ant, pad, tied-array. Default ant03 on W104. (Jamie S)
  • For Tid, determine which antenna is scheduled in block-schedule and modify setup files (Cormac, Shinji, Phil)
  • Xcube developments by August session (Xcube, Tasso, Chris) Updated


  • Check on Mp power-up of systems (Chris) Done
  • Schedule 32 GHz tests for vt10s (Chris) Done
  • Implement “intents” keyword from Vex schedule into ATNF schedules for auto-phasing (Jamie, Chris) Continuing
  • Fix cdisko to record single polarisation, especially at Cd (Jamie S) Done
  • Check on datarates and disk availability (Chris, Jamie) Done
  • Remote access Ho and Cd via VNC for session. Need ssh tunneling. (UTas) Done
  • Monitoring improvements (Jamie) Done
  • Arrange tests on Curtin Xcube (Chris, Cormac) Continuing
  • Onsource info from ATCA. Fix cgi scripts (Chris) Continuing
  • Mk5 schedules and FS version. Tests needed (Jamie M) Done
