Resumen:
The fine structure of the open cluster NGC 2516 is investigated. This is an extended and relativelyyoung open cluster subtending over two degrees in the sky, situated at just a few hundred parsecs (¡ 400 pc) from the Sun. We collected Gaia DR2 data (G magnitude down to G=19, BP-RP color index, proper motions, and parallaxes) for more than 400000 stars in a region of 6 degrees on a side, and applied our pyUPMASK membership algorithm. Gaia data for the most probable members was cross-matched with available UBVI data. Finally, we run our ASteCA code to obtain the fundamental cluster parameters.
