Data Access

The S-Plus data are accessible by a variety of means:

Data Lab Table Access Protocol (TAP) service

TAP provides a convenient access layer to the S-Plus catalog database. TAP-aware clients (such as TOPCAT) can point to, select the splus_dr1 database, and see the database tables and descriptions. splus_dr1 contains eight tables: stripe82, allwise, des_dr1, gaia_dr2, ls_dr5, ls_dr6, nsc_dr1, sdss_dr14_specobj. The last seven are cross-match tables between S-Plus and the relevant datasets.

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. This includes authenticated access, synchronous and asynchronous queries, TAP 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 S-Plus images. For an example of how to use the SIA service see this Jupyter notebook that describes it for the SMASH data set (about 2/3 the way down the page). For S-Plus the SIA URL is
