Data Access

The DELVE DR1 data are accessible by a variety of means:

Data Lab Table Access Protocol (TAP) service

TAP provides a convenient access layer to the DELVE DR1 catalog database. TAP-aware clients (such as TOPCAT) can point to, select the delve_dr1 database, and see the database tables and descriptions. delve_dr1 contains a table named objects, which is described in the Data Lab table browser.

Data Lab Query Manager

The Query Manager is available as part of the Data Lab software distribution. The Query Manager client provides a Python API to Data Lab database services. These services include anonymous access through synchronous queries of the catalog made directly to the database as well as authenticated access, asynchronous queries, personal database storage, and storage through the Data Lab VOSpace.

Image Cutouts

The Data Lab Simple Image Access (SIA) service provides a fast way to retrieve cutouts from DELVE images processed with the DECam Community Pipeline (Valdes et al. 2014). For an example of how to use the SIA service, see this Jupyter notebook.

Jupyter Notebook Server

The Data Lab Jupyter Notebook server (user authenticated service) contains examples of how to access and visualize the DELVE DR1 catalog.
