cds-question@unistra.fropen-star-clustersccd-photometryproper-motionsWe present CCD photometry and proper motion studies of the two open star clusters NGC 1960 (M 36) and NGC 2194. Fitting isochrones to the colour magnitude diagrams, for NGC 1960 we found an age of 16Myr and a distance of roughly 1300 pc and for NGC 2194 550Myr and 2900pc, respectively. We combined membership determination by proper motions and statistical field star subtraction to derive the initial mass function of the clusters and found slopes of -1.23+/-0.17 for NGC 1960 and -1.33+/-0.29 for NGC 2194. Compared to other IMF studies of the intermediate mass range, these values indicate shallow mass functions. These tables present the complete data of the photometry (Tables 2 and 3) and the proper motion studies (Tables 7 and 9) of the two clusters.2000A&A...357..471Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/357/471CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/349/448 : Open star clusters.
