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 » 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)
  • Review ATCA VLBI configs (Jamie S, Tasso) Done

• 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. (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) Continuing
• Remote access to Ceduna VNC via Hobart? (Tasso, Jamie M.) Continuing
  • VNC within VNC ? (Jamie M, Tasso)

• Remote access to Ww (Stuart, Tasso) Continuing

• Simon Ellingsen complex schedules. Send frequency changes list to Ettore (Parkes) and Quick (Hart) for development of LO setups (Simon, Chris) Updated
  • Rationalise Simon's schedules (Cormac, Simon, Chris)

NEW ACTION ITEMS

• DASPRO for Parkes needs updating to reflect Mars Rx changes (Chris)

• NEXPReS BoD tests and demo would need time around June 2013 (Tasso, Phil) Updated
  • BoD test. Scheduled for 27 June 2013(Chris, Tasso) Done

• Check-list for ASKAP Rx changes. Especially 100 MHz reference for X-band. (Tasso, Suzy).
  • Include on Wiki documentation (Tasso)

• RTFC needs >0.5 hours for Mk5 and complex (e.g Simon's) setups (Phil)

• Eliminate separate rtfc schedules except for special mosed (Cormac)
  • 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)

• X-raid disks failing e.g at Ceduna. Manage at correlator (Cormac, Hayley) Done
  • Sent to correlator for replacement of disk (UTas)
  • Curtin to keep stock of 750 GB disks (from failing set) (Cormac)
  • Curtin has stock of 500 GB spare disks. ATNF also has spares and can provide extras.

• NZ slow transfer issues Resolved
  • Possible cache size in Mk5 sofware. Email to Stuart, Chris, Cormac (Jamie M)

• No phase-cal extraction from Mk5 in LBA corrlator. Inform Hart. (Tasso) Done

• Include Hart 15m availability in LBA. Already in SCHED. Done
  • Include in OPAL
  • Supply web link
  • On wiki documentation
  • Inform Leonid Petrov

• For ATCA include in Wiki log: ref ant, pad, tied-array. Default ant03 on W104. (Jamie S)

• Develop LBA 64 MHz setups for X and K bands (Cormac) Done

• For Tid, determine which antenna is scheduled in block-schedule and modify setup files (Cormac, Shinji, Phil)

• Allow cdisko/server to select 1 x 64 MHz channel (Jamie S) Done
