Greetings, all,

We are happy to announce the release of a new DP0 tutorial, one which illustrates use of the Rubin Science Platform (RSP) API aspect via the TOPCAT Virtual Observatory interactive graphical tool . This new tutorial, called “01. API TOPCAT Bright Stars Color-Magnitude Diagram Tutorial (beginner)” makes use of TOPCAT to search for bright stars in a small region of sky and create a color-magnitude diagram.

This new tutorial can be found at [01. API TOPCAT Bright Stars Color-Magnitude Diagram Tutorial (beginner) — Vera C. Rubin Observatory Documentation for Data Preview 0.2](https://dp0-2.lsst.io/tutorials-examples/api-topcat-beginner.html) .

Best regards,  
Douglas Tucker, on behalf of the Rubin Community Science Team (CST)
