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)
- Guidelines for phasing the atca more 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)
- 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)
- 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?
- Implement automatic re-phasing of tied array at ATCA (Jamie, Chris)
- Warn PIs to re-phase array in schedules. Need 2-3 mins (Phil)
- Check with VPAK on data transfers (Tasso)
- Evaluate effort for data Xfers to Petabyte store. Include UTas, NZ and South Africa (Chris, Jamie, Cormac)
- VLBI archive
- Check with Vince re grid-ftp (Tasso, Chris)
- Push e-VLBI archive to Curtin (Chris)
- Check on Xcube orders from Curtin (Cormac)
NEW ACTION ITEMS
- Mk5B units from Curtin to Hobart (Cormac)
- Scheduling issues with Mk5B losing scans. Issue of delays defined in Vex? Check for Mk5B defaults (Jamie M, Cormac)
- Check for Cd stability improvements after fixed H-maser. (Bad internal connections?) (Brett)
- Enquiry with NZ re rumoured H-maser issues. (Tasso)
- Commission Cd L-band system. Underway. (UTas)
- Fringe testing at Tid. Train Shinji? (Chris)
- Investigate new VSIC for Ho and Cd. Need new PROMs (Chris)
- Control through Monica for remote observing? (Chris)
- ASKAP not working. No fringes in previous sessions. Test and fix (Tasso)
- Mixed mode correlation into RTFC (Cormac, Chris)
- MUST fill in WIKI logs for ALL observations. Lack wastes a lot of time. (All)
STANDING ACTION ITEMS
- Participate in DiFX meeting 24-28 September 2012 (All)
- Participation in Haystack e-VLBI workshop 22-24 October (All)
Next meeting: Tuesday 11 September 2012.
