Abstract: We present an advanced, VO-compliant version of Clusterix, a tool for the determination of membership probabilities in stellar clusters from proper motion data. Clusterix is a web-based, interactive application that allows the computation of membership probabilities from proper motions through a fully non-parametric method. Version 1.0 (http://clusterix.cerit-sc.cz/) was developed as a collaboration between the Masaryk University (Czech Republic) and the Universitat de Barcelona (Spain), as a complement to the WEBDA (http://webda.physics.muni.cz) database of observational data on stars in open clusters. Clusterix 2.0 (http://clusterix.cab.inta-csic.es/clusterix/) is oriented towards the exploitation of Gaia data products. With the participation of the Spanish Virtual Observatory, Clusterix now features an improved user interface for a faster, easier and more accurate interactive definition of the cluster and field proper motion distributions. The system provides fast feedback between membership probability determinations and the distribution of observables for the most probable members and field stars, with graphic tools to display, for instance, photometric diagrams on the fly. Furthermore, Clusterix 2.0 is fully VO-compatible, what opens interesting prospects for the astrophysical exploitation of the improved membership probabilities that will be capable to provide for many open clusters observed by Gaia.
