Actions arising

CARRIED FORWARD/UPDATED/CONTINUING

  • 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.)
    • Need at least 6 cycles for auto-phase = 30secs if 5sec integration.
      • Phase-impact on pahse-ref and claibration? Phase jumps?
      • consult with Ojha re auto-phasecal for TANAMI (ATNF)
  • 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.)
  • 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)
  • 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)

NEW ACTION ITEMS

  • ATCA and Mp 7mm LO setup offsets
    • Check if KVN tests affected. (Chris)
    • Fix Mp losetup (MJK)
  • ASKAP web monitoring
  • For wideband systems more efficient to stop data recording in slews/stops AND better effieciency in correlator.
    • Adopt Mk5 systems?
  • Future for LBA recorders. Discuss at LBA-ops mtg (LBA)
  • Cd upgrades
    • DAS replacement by dBBc (UTas).
    • L-band sensitivity measurements? (UTas)
  • Tid tests for JPL DAS and Mk5c recorder
    • Let JPL know re VDIF format (Chris)
    • Web monitoring? Ports?
  • ASKAP VLBI monitoring (Chris, Jamie S)
  • KVN tests
    • 40/80 GHz possible? Test.
    • Proposal from Richard.
  • Xcube testing (Chris)
  • CABB wide-band proges?
    • Email Tim Bateman and get report (Tasso)

STANDING ACTION ITEMS

  • Plan for replacements of old LBA DAS and some failing recorders.
    • Plans to replace at each station (UTas, CASS)
  • Next LBA Ops meeting 11-12 Feb 2014 at Curtin.
    • Draft block program and speakers before Xmas (Tasso)
    • Book hotels early. List on Wiki. (ALL)
  • Prepare for Feb-March 2014 runs around VSOP sessions. 2-3 days every 9 days. 4 runs (21/2, 2/3, 10/3, 17/3) - ALL
  • VLBI science meeting in 2015 at Darwin/Katherine (NB. Now in 2015!!)
    • Setup LOC, SOC (Tasso, Jim)

Next meeting: TBD (Feb 2014)
