1.3.4. Crossmatch Tool

The Data Lab crossmatch tool (X-match service) allows users to upload their own data tables (with columns for RA and Dec positions), and to efficiently crossmatch them with the tables in the Data Lab databases.

Go to the X-match tool: https://datalab.noao.edu/xmatch.php

The service requires that the user be logged in, because uploading tables to the user’s VOSpace necessitates authentication.
