A Target of Opportunity Observing System for NOAO
Rob SeamanData Products Program29 April 2008
Astronomy is many disciplinesFrom Solar System to Galaxy to CosmosFrom Big Bang to current epochFrom gigayear stasis to explosive detonationPhysics in extreme regimesEarths broadest contextCivilizations ultimate master
Diverse Observing modesClassical observingQueue scheduledSurvey campaignsService staffingRemote staffingKibitzing modesRobotic observingAll share autonomous trends (power tools)
Experimental designObservations serve empirical purpose(s)Archival science is not differentPhilosophical issues cant be ducked:What is a detection?What is an object?What is a process?Software can help or hinder
Astronomical lifecycleAsk questionDesign experimentSubmit observing proposalScheduling constraintsObserving run preparationPick an observing modeTransport data (or VO equivalent)
Astronomical lifecycle 2Reduce dataAnalyze results in contextDeduce sciencePublish to the communityPublish to the publicAsk new questions
Time domainCant afford the cycle overheadMust speed up by several orders of mag.but alsoSchedule is no longer a free parameterPreparation must be complete & explicitContext is everything (sample selection)Competition is fierceThus need new observing mode
