Data simulations / Community challenges Stephan Birkmann / Jeff Valenti 1
Simulator uses Create simulator Performance Description Release simulated data Organize data challenge Release simulator 2
Agree on simulation guidelines Science inputs e.g., simulated spectrum, parameter space Operational assumptions (the rules ) e.g., reset, read, read Instrumental effects to consider e.g., photon noise, read noise, intra-pixel, Presentation of results e.g., PPM vs. wavelength 3
Performance description examples PPM vs. wavelength 6-hr clock time 1 hr R=700 bin R=100 4
How to agree on simulation guidelines? (Very) small working group? 1-2 participants per IDT when? 5
Types of data challenges Types of simulated data Raw images Instrument artifacts Reduced spectroscopy/photometry Model constraints Types of analyses Recover inputs with knowledge of input Recover inputs from blind analysis 6
(Benefits of data challenges) (Build community support) We are beyond this point (List key factors that affect experiment) Data quality issues Model parameters Product of simulation step (Build familiarity with ground system) Standard data products Observing templates Product of simulation step 7
Benefits of data challenges Formulate observing strategy based on... Ability to remove known instrumental effects e.g., persistence, ghosts, jitter Only useful until real data are released Ability to recover input model parameters e.g., composition, thermal structure Useful throughout mission lifetime Inform TAC Allocate observing time wisely Facilitate pipeline algorithm development 8
Participation in data challenges Advantages Craft better proposals Become a recognized expert Advertise instrument capabilities (Obtain funding) Disadvantages May help competing proposals Requires significant effort 9
Which must be done? Would you participate? Create simulator Performance Description Release simulated data Data challenge Release simulator 10
