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
• 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)

• Implement upgrade for programmable cable changes on VLBI DAS. (Chris, Jamie S) continuing
  • Contact Peter Mirtchin re DAS remote cabling changes via VSIC (Tasso)

• 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

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

• Organise e-VLBI demo with Brazil (Tasso)
• eVLBI demo to Korea at K-band (Chris)

• LBA monitoring problems due to ares issues at UTas (Jamie M) ** continuing
  • Need to find alternative access.

NEW ACTION ITEMS

• Ceduna issues persisting. (UTas)
  • Evaluate results of test with Rb vs H-maser at S-band during LBA session (UTas, CASS, Curtin)

• Check with NZ re issues with Ww drives (Tasso)

• Implement larger filesizes for recording (1 minute) since number of files is impacting the PB store (Chris, Jamie)

• Need correlator report on telescope performances before March session (Curtin)

• Need ASKAP data from Nov session. Disk needs to be sent to MRO and data copied (Tasso, Chris)
