Evaluating the LSST Observing Strategy: Metrics

Evaluating the various simulated survey strategies is complex and involves many metrics. We will demonstrate the metrics currently being calculated on the various survey strategies and how they vary between runs. Then we hope to involve the community in a discussion covering (a) how accurate or complete are the metrics relevant to your science? (b) how can we weight different metrics together (or if considering groups of metrics separately, how do we separate them)? and (c) what is reasonable to present to the SCOC (Survey Cadence Optimization Committee)? We will be approaching these questions with the science collaborations independently, but this is a great opportunity to discuss this as an entire community and look at cross-cutting questions. If time is available, we may dive into a deeper discussion of individual metrics or have a short metric hack session.

Please contact lynnej@uw.edu if you would like to contribute to this session.
Planned agenda:
  • Description of current 'key' metrics
    • Galaxy counts 
    • Transient recovery (light curves from PLASTICCS - type IA, kilonova, no lensing) 
    • Astrometry (parallax and proper motion)
    • Solar System metrics 
    • Are we covering the important KEY metrics? Are we missing something (yes, of course)?  
  • What are these metrics telling us so far? - characteristics for baseline, characteristics for other surveys? (comparisons)
  • Discuss how to rank and combine metrics, discuss if any metrics missing, discuss how to give feedback about metrics, offer help with developing or working on metrics
    • Can we set thresholds to guide our internal investigations? How do we rank or compare different surveys for the SCOC?
