Solar system objects in DP0.2
=============================

`LSST’s Data Preview v0.2 <https://dp0-2.lsst.io/>`__ 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 <https://github.com/Small-Bodies-Node/sbsearch>`__ is a
library that is designed to search for comets and asteroids in
wide-field time-domain data sets. `v3 of
sbsearch <https://github.com/Small-Bodies-Node/sbsearch/tree/v3>`__ 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).

(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:

================================ ======================
Object                           Number of observations
================================ ======================
( 65803 ) Didymos                4
2022 SC19                        26
C/2022 R6 (PanSTARRS)            63
C/2019 Q3 (PanSTARRS)            12
C/2022 O1 (ATLAS)                30
C/2023 V4 (Camarasa-Duszanowicz) 26
C/2023 V5 (Leonard)              31
================================ ======================
