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
- 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)
