DESaccess is an open source set of tools to access and analyze astronomical data, used as a primary research tool by hundreds of astronomer around the globe.
Developed at the National Center for Supercomputing Applications (NCSA), DESaccess provides a primary set of basic web applications and a programmatic API to access Dark Energy Survey (DES) release data. It provides an interface to submit asynchronous jobs that perform potentially lengthy operations involving the DES release catalogs stored on the co-located Oracle database. These jobs include executing SQL statements and generating cutouts from the image data given list of positions and desired areal dimensions.
This code repository serves as a public snapshot of the core components of the DESaccess service deployed for the DR2 public data release, including a snapshot of the deployment of the DR2 data release documentation website.
Documentation about this deployment framework can be found in the Sphinx-based documentation system.
