Actions arising

CARRIED FORWARD/UPDATED

• 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

• Guidelines for phasing the atca more often during vlbi observations (ATNF) - to be revisited
• Implement upgrade for programmable cable changes on VLBI DAS. (Chris, Jamie S)

• Update Parkes VLBI notes on Wiki (Jamie, JER, Tasso)
  • Mk5 notes for Parkes on Wiki (Chris, JER, Tasso)
  • Parkes Calibration notes (JER, Ettore)

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

• Proposal for VLBI with GMRT for next round (All) continuing

• Follow-up of zoom-modes for VLBI on atca (Jamie, Tasso) Continuing
• Feed-back on tied-array operation (correlator)

• Report on possible persistent frequency problem at Cd (correlator)

• Plan for VLBI demos with AuScope antennas (UTas)

NEW ACTION ITEMS

• Ww issues at X-band such as pointing to be addressed (AUT)
• Get AuScope fix for Elevation encoder drift to NZ and Parkes (Jim)

• Try automatic pcal via schedules on atca (Jamie S)

• Complete ASKAP data transfers from June observations (Chris, Cormac)

• Fringe tests for Cd at 25 GHz (Chris, Jamie M)
• Updated Cdisko2 at Ho and Cd (Chris, Jamie M)

• Check mixed-mode correlation issues with Adam while he is at Curtin. Ascertain extent (Cormac)

• Investigate sideband separation at atca (week fringes seen on inversion) (Chris, Cormac, Jamie)

• Transfer of MK5 data from Parkes from last session (Chris)
• Mk5 disks (2 TB+) to Tid for next session (Chris)

• Distribute LBA schedules by Monday evening. Hart to be notified (Cormac)

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

• Arrange observers for 12-15 August session (Chris is unavailable) (Tasso)

• Transfer of LBA archive from Curtin to ATNF needs route. Firewall issues? (Chris, Shaun)

• Contact Peter Mirtchin re DAS remote cabling changes via VSIC (Tasso)

Next meeting: Wedn 07 September 2011, 14:00 AEST (04 UT)
