HDMC VxO SPASE June 2008 Event tables management in AMDA Time (or Event) Tables are collections of times when ‘something’ happens or time spans when some conditions are true. Currently produced and managed « manually » by the scientists for their own use or for a community of users. AMDA is increasing the possibilities of these tables : it provides a generic tool to create, manage and share these objects How to generate Time tables with AMDA : With the search tool based on mathematical criteria applied to the contents of the data With the visual search tool AMDA can ingest Time Tables : Coming from statistical studies ( e.g magnetopause crossing lists ) Produced by users Current status:
