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, TNOs
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.
