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)
Next meeting: 23 April 2012
