CARRIED FORWARD/UPDATED/CONTINUING

• Consolidation of the LBA Archive to include all ATNF + Swinburne + Curtin correlated LBA data. Should also add in eVLBI output data. Maintain complete archives at Curtin and ATNF (ATNF/Curtin)
  • ATNF to develop online access to this archive (ATNF) - Continuing
  • Arrange ATOA on-line access to archive (ATNF)
• Copy LBA data archive from Curtin to ATNF (Curtin, Chris) continuing
• Transfer of LBA archive from Curtin to ATNF needs route. Firewall issues? (Chris, Shaun)

• Guidelines for phasing the atca more often during vlbi observations (ATNF) - to be revisited
  • Try automatic pcal via schedules on atca (Jamie S)
  • test time for K-band tied-array phase tests at ATCA (Jamie, Richard)

• Investigate/implement mixed mode correlation (64 MHz & 4 x 16 MHz) at Curtin correlator (Cormac, Chris) continuing

• Need to train observers for all antennas as more remote observing is anticipated (Tasso) continuing

• Investigate Rx for Methanol at ASKAP. Very desirable and usable. (Tasso)

• CABB test version records no Tsys. Need to fix before LBA session. Consult with WEW.(Jamie)

• Clock problems in Cd continuing. Need attention. (All)

• Brazil e-VLBI (Tasso)

• VPAK trnasfers. Sam Morrison till July 2012. Future? (Tasso)

NEW ACTION ITEMS

• For Mk5 observations at Parkes 2 people are not enough. Need more observers (GA, CASS)

• Storage needs at antennas (ATNF)

• Wiki logs from ASKAP (Chris)
• Need RTFC to Tid (Chris, Shinji)

• 32 GHz VLBI tests
  • Check for frequency offsets at ATCA. Talk to engineers. (Jamie)
  • 32 GHz radiator at ATCA?
  • Do Tid-Mp-ATCA tests
  • Do Mp-Tid pilot test?

• Check Mk5b channels at Parkes and compare with Hart (Chris, Jonathan)

• Tests on 16 TB Mk5 modules at UTas as issues at AuScope antennas (Jamie McCallum)

• Radioastron support at Parkes for August 24? (Phil)

• Test and commission new VSIC remote operation. (Chris)
  • Mp already done. Implement at Parkes.

• Commission Cd L-band system (UTas)

• Procure Xcube systems ? (CASS)

STANDING ACTION ITEMS

• Organise next DiFX meeting in September 2012 (Chris). Participate (All)
• Participation in Haystack e-VLBI workshop 22-24 October (All)

Next meeting: 16 August 2012
