J-M Petit, TNO2006, Catania. July 03-07, 2006
Quick Summary (1)
● ~400 sq.deg. of discoveries near the Ecliptic
● ~350 sq.deg. with the planned observing sequence
● 40 sq.deg. in the galactic plane
– not properly suited for TNO search
● ~310 sq.deg. of good, fully useable data
– currently 404 discovered objects (not all fields searched yet)
– 244 objects characterized (not all fields characterized yet)
J-M Petit, TNO2006, Catania. July 03-07, 2006
Quick Summary (2)
● Fully characterized and tracked sample from 2003
– 94 fields
– 79.14 sq.deg.
● MegaCAM coverage: 0.9 sq.deg. ● some overlap● chips failure on some blocks
– 74 discovered objects
– 55 objects with accurate orbit
● Full characterization of discovery efficiency with:
– magnitude
– rate of motion
