Actions arising


  • LBA data archive consolidation and copy at CASS. (CASS, Curtin)
    • LBA data archive. Need ATNF disk space (Chris,Tasso, Shaun) Continuing
  • ATCA phasing. Check performance and implementation (Jamie S, Richard) Updated
    • Definitely need >200 mJy calibrators. Stress in documentation. (ATNF)
    • Ask PIs to nominate phase-cals and check fluxes BEFORE scheduled observations (Phil, Jasmie S)
    • Extract phasecals from Vex files and check at ATCA before run (Chris, Jamie S.)
  • ATCA Tsys via CABB (CASS) Updated
    • Consult with Carrad and Sault about Tsys implementation on the CABB (Tasso)
  • 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)
  • 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
  • For ATCA include in Wiki log: ref ant, pad, tied-array. Default ant03 on W104. (Jamie S, ALL observers)
  • Implement “intents” keyword from Vex schedule into ATNF schedules for auto-phasing (Jamie, Chris) Continuing
  • Curtin Xcube testing. Unit install at ASKAP. (Chris, Cormac, Tasso) Continuing
  • Onsource info from ATCA. Fix cgi scripts (Chris) Continuing
  • DA role during LBA sessions (Phil, Tasso, Jamie S)
  • Procedures for raising Ho observers on Skype. Telephone? (UTas)
    • Implement lists on Skype and/or Wiki for observers(ATNF)
  • Get Ww FS log comments onto Wiki. Use UTas “floggit” script and automate? (Stuart, Chris, Jamie M.)
  • Need VSIC remote switch for Tid to avoid cable problems.
    • Cables needed from ATNF (Chris, Jamie S.)
  • Fix recmon to track correct experiment name, especially due complex recordings for Ellingsen (Chris, Jamie S)
  • List Mk5 rtfc times for each observation from schedules (Cormac, Chris)
  • Arrange support for spacecraft observations on 29 Dec. (ATNF)


  • Check disk packs at narrabri and whether more are needed for emergency disk usage (Jamie S, Chris)
  • Check Mp at 22 and 32 GHz for coherence and fringes (Chris, Jamie S, Tasso, Phil)
    • Need Mp visit to setup K-band
    • Check re moisture in mm-Rx window.
  • Encourage and train PIs and CoIs for VLBI observing (Tasso)
  • RadioAstron schedules and check setups (Chris)
  • Mk5C test with Tid (Chris, Shinji)
  • Use new numbers for ATCA (4077 for DA; 4078 for Observer)


  • Plan for replacements of old LBA DAS and some failing recorders.
    • Plans to replace at each station (UTas, CASS)
