Abstract
It is very difficult to find archival images of
solar system objects.
While regular archive searches can find
images at a fixed location,
they cannot find images of moving
targets. Archival images have become
increasingly useful to
galactic and stellar astronomers the last few
years but, until
now, solar system researchers have been at
disadvantage in this
respect. The Solar System Object Search (SSOS) at
the Canadian
Astronomy Data Centre allows users to search for images
of moving
objects. SSOS accepts as input either a list of
observations, or
an object designation, or a set of orbital elements,
or a
user-generated ephemeris for an object. It then searches
for
observations of that object over a range of dates. The user
is then
presented with a list of images containing that object
from a variety
of archives. Initially created to search the CFHT
MegaCam archive,
SSOS has been extended to other telescope
archives including Gemini,
Subaru/SuprimeCam, HST and several ESO
instruments.
