Solar system objects in DP0.2

LSST’s Data Preview v0.2 is simulation of 300 deg2 of sky, observed with an LSST-like camera and cadence. Solar system objects are not included in the simulated DP0.2 data, but one can still search the DP0.2 metadata for coverage of a their ephemerides. This document serves as a resource to share information on those targets.

sbsearch results (lead: Mike Kelley)

sbsearch is a library that is designed to search for comets and asteroids in wide-field time-domain data sets. v3 of sbsearch is in development (as of Jan 2025), but has been successfully used to find solar system objects in DP0.2 data. The following figure serves as an example of such a search for comet C/2022 R6 (PanSTARRS).

A looping line with small boxes sparsely covering it. C/2022 R6 (PanSTARRS) ephemeris and the DP0.2 images that include it.

Based on a search for a small number of objects, the following solar system objects have been “observed” by the DP0.2 data set:
