VLBI/eVLBI operations and technical meeting, Perth, 11-12 Feb 2014 —————————————————————————————— ACTIONS list The ordering of this action list roughly follows the agenda of the meeting. Some actions were carried forward and modified from the previous meeting(s). A consolidated and integrated list is given here. - ACTION: Proposals and scheduling * Monitor available LBA time and over-subscription (Phil) - CONTinuing * Increase LBA time? (Phil) - CONT * Encourage more ToOs qnd NAPAs(ATNF) - CONT * Insert sentence re ToO and NAPA in call for proposals (Phil) * More sessions of fewer days (e.g methanol cadence)?
