J/AJ/133/917       HST photometry of two NGC 4214 clusters        (Ubeda+, 2007)

The young stellar population of NGC 4214 as observed with the Hubble Space Telescope. I. Data and methods. Ubeda L., Maiz-Apellaniz J., Mackenty J.W. <Astron. J., 133, 917-931 (2007)> =2007AJ....133..917U (SIMBAD/NED BibCode)
ADC_Keywords: Galaxies, nearby ; Associations, stellar ; Photometry, HST Keywords: galaxies: individual (NGC 4214) - galaxies: star clusters - galaxies: stellar content - stars: early-type - stars: luminosity function, mass function Abstract: We present the data and methods that we have used to perform a detailed UV-optical study of the nearby dwarf starburst galaxy NGC 4214 using multifilter Hubble Space Telescope WFPC2 and STIS photometry. We explain the process followed to obtain high-quality photometry and astrometry of the stellar and cluster populations of this galaxy. We describe the procedure used to transform magnitudes and colors into physical parameters using spectral energy distributions. The data show the existence of both young and old stellar populations that can be resolved at the distance of NGC 4214 (2.94Mpc), and we perform a general description of those populations. Description: The WFPC2 images were acquired in two programs: 6569 (principal investigator [PI]: J. MacKenty) and 6716 (PI: T. Stecher). File Summary:
