Summary, Delegate Assembly Fri Sep 29: DP0.3 Simulation Overview

Pedro Bernardinelli and Jake Kurlander, who helped to generate the simulated solar system observations being used for DP0.3, gave a presentation about the details of the simulated populations and a tutorial with a notebook that shows how to retrieve and identify object populations and plot their properties. They also provided an overview of known issues with the simulation and discussed possible improvements for the future.

Thank you very much Pedro and Jake!


DP0.3 Overview – We present an introduction to the LSST Data Preview 0.3. This data preview aims to simulate what the data catalogs provided by the LSST will look like after one as well as ten years of survey operations. As such, this simulation includes a wide variety of Solar System populations, from near Earth objects (NEOs) to distant trans-Neptunian objects, as well as the more "transient’’ interstellar and long period comet populations. For many of these populations, the number of simulated objects correspond to the same order of magnitude as expected from the real survey. This simulation simulates detection in individual images with their corresponding uncertainties, orbit linking given the survey requirement goals, and had their photometric parameters recovered using a common model for all populations. We also describe some of the known issues with DP0.3, and expected improvements from the next few months. Finally, we present a simple tutorial where the user can select individual information for a given Solar System population.

During the assembly, the second cell (the first query) of this notebook failed to execute. A fix is currently being worked on by Rubin staff. See New DALFormatError for a DP0.3 query for details.
