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)
  • 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

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

• 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 and report in Korea meeting (Xcube, Tasso, Chris) Updated

• Implement “intents” keyword from Vex schedule into ATNF schedules for auto-phasing (Jamie, Chris) Continuing

• Arrange tests on Curtin Xcube (Chris, Cormac) Continuing

• Onsource info from ATCA. Fix cgi scripts (Chris) Continuing

• Investigate desirability of upgrade NZ connection from 1 Gbps to 10 Gbps (All) Continuing

NEW ACTION ITEMS

• Investigate remote resets on PMON at ATCA? Now need DA (Phil, Jamie)
• DA role during LBA sessions (Phil, Tasso, Jamie S)

• Check Mp at 22 and 32 GHz for coherence and fringes (Chris, Jamie S, Tasso, Phil)

• Procedures for raising Ho observers on Skype. Telephone? (UTas)

• 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. Check at ATNF (Chris, Jamie S., Tasso)

• Trial Ke and Yg remote monitoring. Check network loading (Jamie & Jamie)

• Spare 500 GB disks from ATNF to UTas for Xraid rebuilds (Chris, Jamie M.)

• Keep vc numbering for rtfc but use separate schedules only when necessary (Phil, Cormac)

• 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)

• Prepare for next LBA session on 18-26 November 2013 (All)
• Arrange support for spacecraft observations on 29 Dec. (ATNF)
• 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

• Prepare for special arrangements to cope with possible PB store relocation and ~6-week break (Cormac, All)

STANDING ACTION ITEMS
