The DELVE data are accessible though several means:

Data Lab Table Access Protocol (TAP) service

TAP provides a convenient access layer for the DELVE catalog database tables. TAP-aware clients (such as TOPCAT) can point to https://datalab.noirlab.edu/tap, select the delve_dr1 or delve_dr2 database, and see the database tables and descriptions. Descriptions of the associate tables can also be found on the Data Lab table browser. Primary measurements are contained in the delve_dr1.objects and delve_dr2.objects tables.

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. Note that DELVE process images with the DES Data Management Pipline (Morganson et al. 2018), which differs slightly from the DECam Community Pipeline.

Jupyter Notebook Server

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