 +**Actions arising** 
 + 
 +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) 
 + 
 +  *  Implement upgrade for programmable cable changes on VLBI DAS.  (Chris, Jamie S) ** continuing ** 
 +    *  Contact Peter Mirtchin re DAS remote cabling changes via VSIC (Tasso) 
 + 
 +  *  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 ** 
 + 
 +  *  Investigate Rx for Methanol at ASKAP. Very desirable and usable. (Tasso) 
 + 
 + 
 + 
 + 
 +NEW ACTION ITEMS 
 + 
 +  *  CABB test version records no Tsys. Need to fix before LBA session. Consult with WEW.(Jamie) 
 +  *  ATCA timing offset between DAS1 and DAS2 with Huygen'​s cable. Align before session (Jamie) 
 +  *  VSIC needs rewiring before tests (Chris, Jamie) 
 + 
 +  *  Large (hours) single data files in last session. Software written to split. Need to transfer split files (Chris) 
 +  *  DASPRO needs changing on wiki to reflect current practice (Chris, Cormac) 
 + 
 +  *  Need ASKAP data to Curtin for mixed mode correlator tests (Tasso, Chris) 
 + 
 +  *  Problems at Ho due to power failure of UPS. May help to have better integration of observing during sessions (UTas, ATNF) 
 + 
 +  *  Clock problems in Cd continuing. Need attention. (All) 
 +    *  Check finer sampling for GPS-Hmaser data (Brett) 
 +    *  Check with WEW re any H-maser issues in Cd (Tasso) 
 +    *  Email Anton Pavlenko in Russia re H-maser issues (Brett) 
 +    *  Organise Russian visit if necessary. (May also check MRO H-maser). (Tasso, Brett) 
 +    *  Compare Ho Russian H-maser- GPS with Cd results. Look at IVS data. (Brett, Oleg) 
 + 
 +  *  Get Mk5 disks to AuScope stations for LBA session (ATNF) 
 + 
 +  *  Brazil e-VLBI (Tasso) 
 + 
 +  *  VPAK trnasfers. Sam Morrison till July 2012. Future? (Tasso) 
 +    *  Open Ho ports to VPAK (UTas) 
 + 
 +  *  Organise next DiFX meeting in September (Chris) 
 +  *  Participation in Haystack e-VLBI workshop 22-24 October (All) 
 + 
 +  *  MWA is decommissioning XRAID chassis. Acquire some for spare and extra set at Narrabri (Chris, Jamie) 
 + 
 +
