  2. DECam NEO Search Lori Allen (NOAO) David Trilling (NAU) Tim Axelrod (LSST) Ed Beshore (Catalina Sky Survey) Mark Trueblood (NOAO) The etendue of DECam/Blanco surpasses that of all existing NEO searches. DECam Community Workshop 19.08.11

  3. DECam NEO Search Size distribution of NEOs: reasonably well known to few hundred m predicted >140m ~15,000 (Harris 2008); about 1/3 cataloged little known about population in the 50-100m size range -- are small NEO isotropic on the sky? Characterization of Inner Earth Objects: semimajor axis < 1 AU little is known about size distribution or other properties DECam Community Workshop 19.08.11

  4. DECam NEO Survey A strawman observing plan: 20-night block for opposition search 60 pointings, each observed 4 times per night 10 nights discovery / 10 nights recovery enables follow-up of faint objects (V=24) Twilight search for earth-crossing objects 1 hour each at morning, evening twilight piggyback on DES or other ? DECam Community Workshop 19.08.11

  5. predicted result • Scale G96 (Catalina Sky Survey) • by aperture, fov, nights observed • 1,000 objects in 10 nights • 80% fainter than any existing • survey would detect DECam Community Workshop 19.08.11

  6. software MOPS CSSP DECam Community Workshop 19.08.11

  7. timeline • Fall 2011: get MOPS and CSSP running, look at parallelizing (simulated data) • Winter/Spring 2012: obtain commissioning / SV data, refine pipeline • Spring 2013: Observe / Survey DECam Community Workshop 19.08.11
