Actions arising

CARRIED FORWARD/UPDATED/CONTINUING

• 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 ÒË 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 ò??bestò?? 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 ò??check-listò?? 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

NEW ACTION ITEMS

• Check on Mp power-up of systems (Chris) Done

• Schedule 32 GHz tests for vt10s (Chris) Done
