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
• 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
• Notify WEW of times of any ATCA delay jumps (Correlators)
• Correlate Boolardy geodetic data to get better position, before next session. (Curtin) - in queue

NEW ACTION ITEMS

• Test ATCA data from the vlbi_64_1_tda mode and compare 64 MHz and 1 MHz modes (Jamie S.)
  • Guidelines for phasing the atca more often during vlbi observations (ATNF)
  • Clarify availability of atca data during VLBI. Include in letter to PIs to allow informed choice (ATNF)
• Inform PIs of ~150ns delay difference in polarizations at the atca (ATNF, Correlator)
• Publicise availability of OH and S-band form next period at atca due to the L/S upgrade.(ATNF)
• UTas is implementing a pre-planning meeting to plan Rx setups and avoid mix-ups. Must have setup instructions at least 2 days before session. (UTas)
• New equipment in Ceduna town to mitigate interference to wi-fi link to the telescope. New 5 GHz wi-fi operation. (UTas)
• Address XRAID issues at Tid. Power-cycle testing and/or upgrade hardware. Swinburne could be source of XRAID. (Shinji, Chris)
• Urgent input to JPL re Tid scheduling beyond 25 Oct. (Shinji, Phil)
• Check cx016b data and correlate full dataset when all data at Curtin. (Correlator)
• Implement upgrade for programmable cable changes on VLBI DAS. Testing needed. (Chris, Jamie S)
• Fix faulty CAVE nodes (04 and 07) - (Chris)
• Test Mp lo_setup after synthesiser upgrade. Test cm observation online and need full test for K-band (ATNF, Tasso)

Next meeting: TBD ---> 10 November 2010.
