Cordoba Carte du Ciel-Astrographic Catalog, CCAC
Listed in IVOA Registry (Virtual Observatory)
Based on stellar positions and proper motions, we aim to re-analyse the region of the controversial open cluster Collinder 132.
Description
Methods. We have developed a model which analyse the proper motion distribution and the stellar density to find moving groups.
The astrometric data was obtained from four Carte du Ciel (CdC) and one Astrogaphic Catalogue (AC) plates of the Cordoba Astronomical Observatory collection (Argentina). We detected an open cluster from the field stars and calculated the mean proper motion and the membership probabilities of the stars of the region. We report new coordinates of its centre RAc=108.347deg, DEc=-31.011deg, the components of mean proper motion mu_RA_cosDE=-2.62+/-0.44mas/yr, mu_DE_=4.79+/-0.88mas/yr. 11 stars are astrometric members giving a value of 370 for the cluster angular diameter. 6 stars fullfill astrometric and photometric analysis for being cluster members and locate the cluster at 360pc from the Sun.

An over-density in the VPD was found after removing the cluster members, consequently a simple model for the proper motion distribution of an association and of the field was adopted. We report the components of the association mean proper motion mu_RA_cosDE=-1.38+/-0.14mas/yr, mu_DE_=2.26+/-0.16mas/yr. 174 astrometric members were found while 11 members have been located between 417 and 660pc from the Sun by Tycho-2 photometry.
