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)

4
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

• More quantitative results will appear in the
  coming paper presenting the 2003 data release of
  CFEPS
• Stay tuned !
