Vera C. Rubin Observatory Documentation for Data Preview 0.2 (DP0.2)

This site provides information about the Rubin Observatory’s Data Preview 0.2 (DP0.2).

DP0.2 Release Date: June 30, 2022

Data Preview 0 (DP0) is the first of three data previews during the period leading up to the start of Rubin Observatory Operations. The goals of DP0 are to serve as an early integration test of the Legacy Survey of Space and Time (LSST) Science Pipelines and the Rubin Science Platform (RSP), and to enable a limited number of astronomers and students to begin early preparations for science with the LSST.


To become a delegate and access DP0, see the Getting started with DP0 checklist.

Term definitions are provided on the Rubin Observatory Glossary & Acronyms webpage.

Resources for DP0 delegates

The term “delegate” refers to the 600 data rights holders who have accounts in the Rubin Science Platform (RSP) and access to the DP0 data sets.

DP0.2 data products

The data set used for DP0 is the 300 deg2 of simulated, LSST-like images and catalogs generated by the Dark Energy Science Collaboration (DESC) for their Data Challenge 2 (DC2).

DP0.2 data access and analysis tools

The Rubin Science Platform (RSP) is the web-based service for Rubin data access and analysis. Step-by-step instructions for RSP use are provided.


Tutorials include hands-on executable tutorials and demonstrations based on science use cases for learning to use the RSP and the LSST Science Pipelines.
