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)

• ATCA Tsys via CABB (CASS)
  • Tsys at ATCA still not available in CABB.
  • Discuss with WEW (Jamie S) Done
  • Investigate implementation by Bob Sault (Tasso)

• Observer training and remote observing (Tasso)

• Wiki logs (All)
  • Annual “best” wiki-log competition. To be judged by correlator. (Tasso)

• Schedule more 32 GHz tests with ATCA? (Phil)
  • Do local VLBI test between 2 ATCA antennas to check local issues (Chris, Jamie S)

• NSW firewall issues. Test with eVLBI (Chris)

• NEXPReS BoD tests and demo would need time around June 2013 (Tasso, Phil)
  • Distributed correlation with Curtin (Cormac, Chris)
  • BoD test (Chris, Tasso)
  • COMBINE the 2 tests? (Tasso)

• Pawsey centre access for VLBI and eVLBI (Chris, Cormac)

• Linear to Circular polarisation conversion. Most immediate for ASKAP data. (Chris, Richard, Cormac)

• Monitoring “check-list” for ATNF telescopes (Chris, Jamie S)

NEW ACTION ITEMS

• Rx selection at Parkes is not obvious. Modify atsnap to remind Rx selection (John, Chris)

• DAS1 stats at ATCA show problems. Investigate (Jamie S)

• ASKAP antenna drive issues to be investigated (Tasso, Mike Kesteven)
  • Implement EPICS interface for ANT29 and VLBI (Chris)

• Hobart operational issues
  • DAS profile accidental overwrite. Implement counter measures (UTas)
  • Synthesiser frequency offsets confusiing. Need procedures to prevent (Brett)
  • Resolve issues with default Hobart disk for fringe checks (Jamie M)

• Use fauto at Ho and Cd during setup and fringe testing (Brett, Chris)

• Procedures in drudg and FS to enable rtfc during runs (Chris, Cormac, Jamie M)

• Flipped data for 64 MHz at Tid. Provide stand-alone data flipping program to Curtin (Chris)
• Check data transfer procedures from Tid for rftc. Use ssh and reverse tunnel? (Chris, Shinji)

• NZ transfer speeds to pbstore need to be improved. (Chris, Cormac, Stuart)

• ASKAP Vex schedules do not support rtfc without mods (Cormac, Chris)
  • New version of SCHED to be tried out. This should support correct ASKAP Vex (Cormac)

• Need to change SCHED to implement VDIF output. Needed by DiFX corrlator (Cormac, Chris)

• Block schedule may create confusion when Mk5s are scheduled in LBA. Need to expand mode description and educate PIs (Phil, Cormac)

• Next LBA run 13-18 June clashes with ATUC meeting on 13 June. Manage conflict (ATNF)

STANDING ACTION ITEMS

Next meeting: 6 June 2013, in time for June 13-18 LBA session.
