I hope this helps.

LSST will do a complete survey of KBOs brighter than 24th mag (of
order 100 km, a sample of order 5 104 objects). But most of these will
already be discovered byPanSTARRS, etc. LSST will get colors and light
curves.? KBOs move 1? per hour. Thus observe a given field 1 hour to
discover KBOs to 26.5 mag (with an 8-meter class incarnation).
Observing the same field three times over two years yields a good
orbit. ? Observing a series of fields equally spaced along the
ecliptic (±20°) allows full study of the dynamical structure of
theKuiper Belt. This requires that LSST be able to sample the full
ecliptic plane. ? If we spend 10% of the LSST observing time on this
mode, we will discover roughly 100,000 faint KBOs.
