J/A+A/505/1129      BVRIJHK and proper motions in NGC 6253     (Montalto+, 2009)

BVRIJHK photometry and proper motion analysis of NGC 6253 and the surrounding field. Montalto M., Piotto G., Desidera S., Platais I., Carraro G., Momany Y., De Marchi F., Recio Blanco A. <Astron. Astrophys. 505, 1129 (2009)> =2009A&A...505.1129M
ADC_Keywords: Clusters, open ; Photometry, CCD ; Proper motions Keywords: techniques: photometry - open cluster and associations: individual: NGC 6253 Abstract: We present a photometric and astrometric catalog of 187963 stars located in the field around the old super-metal-rich Galactic open cluster NGC 6253. Description: The total field-of-view covered by the catalog is 34'x33'. In this field, we provide CCD BVRI photometry from the MPG/ESO 2.2m telescope. For a smaller region close to the cluster's center, we also provide near-infrared JHK photometry from the Anglo-Australian 3.9m Telescope and from the 2MASS. We derived relative proper motions and calculate cluster membership probabilities. File Summary:
