This is a two day meeting, focusing on each of the key topics. Invited talks of 20 minutes and contributed talks of 12 minutes are foreseen, both including time for discussion. In addition a 30 minute review talk will be scheduled in which an overview of the field of modern astrometry and its science applications will be given.
Presentations and posters available online
PDF versions of the presentations and posters from this focus meeting can be found online at zenodo.org.
