• SCHED developments (Cormac) - Phase A is completed.
• cdisko developments (Jamie Stevens and Chris Phillips) - Major update completed. Incremental improvements continuing.
• Mk5 disk acquisition (ATNF/Curtin) - Completed with 14 x 8TB disk-packs bought by ATNF in early 2010.

** List below annotated on 4/8/10

CARRIED FORWARD

• 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

NEW Action Items

• Investigate more efficient VLBI observing support at Parkes. Current actions mainly pushing the alarm button. Check possibilities of local support (Tasso) - to be revisited after remote control implemented at Parkes next February.
• Implement Mk5b eVLBI operation (Chris) - postponed till Mk5b eVLBI tests are feasible later in the year.
• Mk5b operations at correlator (Curtin) - continuing
  • Mk5b test data to Curtin (UTas)
  • Test with Mopra (Chris, UTas)
  • Parallel LBA amd Mk5 test data (UTas, Cormac) - to be arranged
• Consult with WEW on cause of intermittent clock jumps and delay between polarisations in Dec'09 data (ATNF) - changed to notifying WEW of times of jumps.
• Correlate Boolardy geodetic data to get better position, before next session. (Curtin) - in queue
• Investigate reported intermittent data corruption issue. Check vsib header on a whole session. (Curtin/Chris) - postpone till problem re-occurs and can be investigated
• Continue practice of recording and keeping ~30min of good data from fringe tests, as standard sources of correlation testing. Call by the person doing the RTFC (All) - Implemented

Next meeting: Wedn 04 August, debrief from VLBI session
