Abstract
We present first and preliminary results of a study on the open cluster population seen against the Gum Nebula. This is a very large and nearby emission gas structure covering from l=240° to l=270° and from b=+8° to b=-15°, approximately. Taking advantage of the impressive precision and depth (G≈ 20) of data provided by the Gaia mission (EDR3) and that we have now two powerful tools for an automated analysis of open clusters data, ASteCA and pyUPMASK, we started a project aimed at reanalizing the fundamental parameters of several dozens of open clusters located in the Gum Nebula area.
