Data Access

The DES DR1 and DR2 data are accessible by a variety of means:

Data Lab Table Access Protocol (TAP) service

TAP provides a convenient access layer to the DES DR1 and DR2 catalog databases. TAP-aware clients (such as TOPCAT) can point to, select the des_dr1 or des_dr2 database, and see the database tables and descriptions. des_dr1 contains fourteen tables, with main containing the primary object photometry. des_dr2 contains nine tables, with main containing the primary object photometry. For a one-line description of all of the tables, see the overview page. To view the schema of the tables, use the Query Tool.

Data Lab Query Manager

The Query Manager is available as part of the Data Lab software distribution or through the Data Lab Jupyter Notebook server. The Query Manager client provides a Python API to Data Lab database services. For the DES DR1 release, these services include anonymous and authenticated access through synchronous and asynchronous queries of the catalog.

Image cutouts

The Data Lab Simple Image Access (SIA) service provides a fast way to retrieve cutouts from DES images. For an example of how to use the SIA service, look at the example Jupyter notebooks.

Jupyter Notebook Server

The Data Lab Jupyter Notebook server contains examples of how to access and visualize the DES DR1 and DR2 catalogs (account creation required).
