Data Access

The NSC 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 NSC catalog database. TAP-aware clients (such as TOPCAT) can point to, select the nsc_dr1 or nsc_dr2 database, and see the database tables and descriptions. Both nsc_dr1 and nsc_dr2 contains five tables: chip, exposure, coverage, object, and measurement.

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. Services include 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 NSC images. This service will be available for NSC DR2 in the near future.

Jupyter Notebook Server
The Data Lab Jupyter Notebook server contains examples of how to access and visualize the NSC catalog.
