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)
- Arrange ATOA on-line access to archive (ATNF)
- Copy LBA data archive from Curtin to ATNF (Curtin, Chris)
- Transfer of LBA archive from Curtin to ATNF needs route. Firewall issues? (Chris, Shaun)
- Check with Vince re grid-ftp (Tasso, Chris)
- Push e-VLBI archive to Curtin (Chris)
- Phasing the ATCA often during vlbi observations (ATNF)
- Try automatic pcal via schedules on atca (Jamie S)
- test time for K-band tied-array phase tests at ATCA (Jamie, Richard)
- Implement automatic re-phasing of tied array at ATCA (Jamie, Chris)
- Warn PIs to re-phase array in schedules. Need 2-3 mins (Phil)
- 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)
- CABB test version records no Tsys. Need to fix before LBA session. Consult with WEW.(Jamie)
- Brazil e-VLBI (Tasso)
- VPAK transfers. Future? (Tasso)
- Evaluate effort for data Xfers to Petabyte store. Include UTas, NZ and South Africa (Chris, Jamie, Cormac)
- Need RTFC to Tid (Chris, Shinji)
- For Mk5 observations at Parkes 2 people are not enough. Need more observers (GA, CASS)
- Storage needs at antennas (ATNF)
- 32 GHz VLBI tests
- Check for frequency offsets at ATCA. Talk to engineers. (Jamie)
- 32 GHz radiator at ATCA?
- testing?
- Check for Cd stability improvements after fixed H-maser. (Bad internal connections?) (Brett)
- Commission Cd L-band system. Underway. (UTas)
- Mixed mode correlation into RTFC (Cormac, Chris)
- MUST fill in WIKI logs for ALL observations. Lack wastes a lot of time. (All)
NEW ACTION ITEMS
- Check that schedules have the 8441 MHz centre frequency set at ASKAp
- Schedule more fringe tests at ASKAP to monitor system stability (Tasso)
- Develop procedures for mixed-mode correlation tests (Chris, Cormac)
- L-band tests with Cd for Rx commissioning
- Prepare schedules for possible Friday slots (Chris)
- Develop Java-scripts for rtfc control (Chris, Jamie)
- Check disks for Yd antenna for run (Jamie M)
- Check disks shipped from Curtin to Hobart (Jamie M)
- Develop procedures for phase-tying at the ATCA (Jamie, Chris)
- Tweak Ojha schedules for Mk5 data transfer for rtfc (Cormac, Chris)
- Revised schedules to be circulated (Phil)
- Check new correlator config for VLBI at ATCA (Jamie)
- Check on data transfer issues
- Xfers con trolled from Curtin? (Cormac)
- Communicate with VPAK (Tasso)
STANDING ACTION ITEMS
- Participate in DiFX meeting 24-28 September 2012 (All)
- Participation in Haystack e-VLBI workshop 22-24 October (All)
- LBA ops/technical/e-VLBI annual meeting in Hobart 12-13 February? (All)
Next meeting: TBD (Tuesday 16 October 2012?)
