Workflows in Astronomy(Survey Pipelines & Virtual Observatory)Pavlos Protopapas, University of Pennsylvania Virtual Observatory: Set standards Dataformat (VOTable) Query Language (SIAP, ConeSerach,ADQL) Registries Pipelines : (photometry, World Coordinate System etc) Example: Solar System (planets, asteroid, TNO’s plutinos) Fast moving objects (1-2 days can be resolved) 2/3 observations enough to set orbit with error circle Look back in time in the VO dbs find observation (run photometry, extract moving object,etc) Keep doing until orbit is well defined – Follow up observation Separate message flow, data flow Event driven (dynamically changing) Routing (change direction) and complexity (if,for etc) Reusability, easy integration VO,Pipeline,Grid. Graduate student must be able to create one of those in a day or two.
