This project is dedicated to the study of open clusters using data from the Gaia catalog. With the results obtained we present a new catalog of open clusters that is constituted of two main parts:

1 - Astrometric membership:

From Gaia DR2 astrometric data we determine the stellar membership using proper motions and parallaxes, taking into account the full covariance matrix.

2 - Distances and ages:

Using the astrometric membership we apply our non-multidimensional global optimization tool to fit theoretical isochrones to determine the distance, age, reddening, metallicity and binary fraction of the clusters.
