  22. MOPS Overview • Identify known objects • Discover new objects • Derive observable parameters • Catalogue objects • Enable solar system science MOPS Training Session, Tucson, AZ

  23. Terminology Review: • Single Occurrence Transient = SOT • A detection that is not at the same position as any other known stationary object in the past 30 (TBR) days • High S/N (HSD) Detection • A detection that has a high probability of being a real object (~>5) • Low S/N (LSD) Detection • A detection that has a low probability of being a real object (~>3) • Data Collection = DC = DB = Database • A generalized database MOPS Training Session, Tucson, AZ

  24. Terminology Review: • Observing Cycle = OC • Integer number incrementing @ 0 UT on day closest to full moon • Synthetic Object • An artificial object with orbital and shape parameters • Derived Object • A synthetic or real object and its parameters derived from observations MOPS Training Session, Tucson, AZ

  25. Terminology Review: • Detection (not an SOT) • A statistically significant collection of pixels after image convolution with a shape kernel • Tracklet • A set of 2 detections that may be observations of the same object • Track • A set of 2 tracklets that may be observations of the same object • Orbit • A six parameter representation of the heliocentric path of an object MOPS Training Session, Tucson, AZ

  39. PS1 Review: DRM Surveys DRM = PS1Design Reference Mission MOPS Training Session, Tucson, AZ

  40. PS1 Review: DRM Surveys >61% of time amenable to discovery of solar system objects. Some of the other surveys can also identify solar system objects. MOPS Training Session, Tucson, AZ

  43. PS1 Review: Bandpasses MOPS Training Session, Tucson, AZ

  44. PS1 Review: Sensitivities The trailed NEO single exposure sensitivityis equivalent to V=23 in g, r, and i bands. The discovery of ‘tracklets’ is equivalentto a 5 sigma limiting magnitude of V=22.8 MOPS Training Session, Tucson, AZ

  45. PS1 Review: Sky-Plane Tesselation Outside view of the celestial sky tesselated into 6252 fields. Of these fields, 5464 have boresight centers > -30° Declination. The 3° field of view of PS1 with an inscribed hexagon of 5.84 square degrees. The twenty percent overlap from a single tesselation due to the circular field of view.

  48. Observing Strategy • Every survey mode obtains at least twoimages at each location separated by a Transient Time Interval (15-30 minutes) • serendipitous positions & colours • Solar system survey re-visits each location after 3-6 days • obtain 3-4 nights/month • ~12 day arc MOPS Training Session, Tucson, AZ
