Abstract:
The populations of small bodies of the Solar System (asteroids,
comets, Kuiper-Belt objects) are used to constrain the origin and
evolution of the Solar System. Both their orbital distribution and
composition distribution are required to track the dynamical pathway
from their regions of formation to their current locations.
We aim at increasing the sample of Solar System objects that have
multi-filter photometry and compositional taxonomy.
We search for moving objects in the archive of the Sloan Digital Sky
Survey. We attempt at maximizing the number of detections by using
loose constraints on the extraction. We then apply a suite of filters
to remove false-positive detections (stars or galaxies) and mark out
spurious photometry and astrometry.
We release a catalog of 1542522 entries, consisting of 1036322
observations of 379714 known and unique SSOs together with 506200
observations of moving sources not linked with any known SSOs. The
catalog completeness is estimated to be about 95% and the purity to be
above 95% for known SSOs.
Description:
We present a new catalogue of Solar System Objects (SSOs) extracted
from the Sloan Digital Sky Survey (SDSS). This SSOs catalogue contains
1533759 observations of 1032357 Solar System objects (asteroids, KBO,
and comets).
The released catalog includes SDSS sources up to 25mag and sets of
photometry and astrometry flags. These sources were classified in a
scheme consistent with Bus-DeMeo taxonomy.
