Beginning of ReadMe : J/PASP/127/31 CCD photometry of NGC 2482 (Krisciunas+, 2015) ================================================================================ CCD photometry of NGC 2482 and five previously unobserved open star clusters. Krisciunas K., Monteiro H., Dias W. <Publ. Astron. Soc. Pac., 127, 31-50 (2015)> =2015PASP..127...31K ================================================================================ ADC_Keywords: Clusters, open ; Photometry, CCD Abstract: We present BV and u'g'r'i' CCD photometry of the central region of NGC 2482. We also present BVu'g' CCD photometry of five clusters that have been poorly studied in the past: Ruprecht 42, Ruprecht 51, Ruprecht 153, Ruprecht 154, and AH03 J0748-26.9, which to our knowledge has not been studied before. Using a global optimization technique that eliminates much of the subjectivity previously inherent in main-sequence fitting studies, we obtain values of the distances, ages, and metallicities of the clusters, with robust estimates of the uncertainties of these fundamental parameters. Four of our clusters are less than 1.3kpc beyond the Sun's distance from the Galactic center and have essentially solar metallicity. The metallicities of those clusters more distant from the Galactic center are consistent with a 0.3dex step to lower [Fe/H] found in other studies. Description: The data presented in this article were obtained by one of us (KK) at Las Campanas Observatory (LCO) using the 1 m Henrietta Swope telescope. Three second exposures of NGC 2482 were obtained in BVgri on 2012 January 6 (UT), along with a 24 s u-band exposure. Longer BV exposures of 150 and 120s, respectively, were taken on 2012 December 21 (UT). For the NGC 2482 images, we used the central 1201x1201 pixels of the CCD chip then in use. The pixel scale is 0.435"; the field size is 8.7' by 8.7'.
