A Target of Opportunity Observing System for NOAO Rob Seaman Data Products Program 29 April 2008
Astronomy is many disciplines • From Solar System to Galaxy to Cosmos • From Big Bang to current epoch • From gigayear stasis to explosive detonation • Physics in extreme regimes • Earth’s broadest context • Civilization’s ultimate master
Diverse Observing modes • Classical observing • Queue scheduled • Survey campaigns • Service staffing • Remote staffing • Kibitzing modes • Robotic observing • All share autonomous trends (power tools)
Experimental design • Observations serve empirical purpose(s) • Archival science is not different • Philosophical issues can’t be ducked: • What is a detection? • What is an object? • What is a process? • Software can help or hinder
Astronomical lifecycle • Ask question • Design experiment • Submit observing proposal • Scheduling constraints • Observing run preparation • Pick an observing mode • Transport data (or VO equivalent)
Astronomical lifecycle 2 • Reduce data • Analyze results in context • Deduce science • Publish to the community • Publish to the public • Ask new questions…
Time domain • Can’t afford the cycle overhead • Must speed up by several orders of mag. but also… • Schedule is no longer a free parameter • Preparation must be complete & explicit • Context is everything (sample selection) • Competition is fierce • Thus need new observing mode
Celestial Transient Events Aitoff projection
VOEvent protocol • IVOA standard • Describe celestial transient events • XML message format • Transport neutral • In coordination with Heterogeneous Telescope Network (HTN)
<VOEvent> • <Who> - provenance • <What> - observations • <WhereWhen> - space/time localization • <How> - instrument configuration • <Why> - semantic characterization • <Citations> - empirical threads
Many VOEvent projects • VO-GCN (Phil, Mike, Caltech, Cal, GSFC) • VOEventNet (Caltech, NOAO, LANL, Cal) • HTN (LCOGT, eSTAR, etc.) • CBAT/MPC/AAVSO/ATEL • GCN/SNEWS/… • NOAO Surveys • NOAO ToO
SIE 554/654 project • System Engineering Process • Use Case driven • SysML • SIE grad student team: • Victor Tenorio (mining) • Ana Catalina Kottman • Anabel Rodriguez • Shahzad Patel (Fall ‘07)
