DESC DC2 Data Release Note
  In preparation for cosmological analyses of the Vera C. Rubin Observatory
Legacy Survey of Space and Time (LSST), the LSST Dark Energy Science
Collaboration (LSST DESC) has created a 300 deg$^2$ simulated survey as part of
an effort called Data Challenge 2 (DC2). The DC2 simulated sky survey, in six
optical bands with observations following a reference LSST observing cadence,
was processed with the LSST Science Pipelines (19.0.0). In this Note, we
describe the public data release of the resulting object catalogs for the
coadded images of five years of simulated observations along with associated
truth catalogs. We include a brief description of the major features of the
available data sets. To enable convenient access to the data products, we have
developed a web portal connected to Globus data services. We describe how to
access the data and provide example Jupyter Notebooks in Python to aid first
interactions with the data. We welcome feedback and questions about the data
release via a GitHub repository.
