Contribution

It introduces a comprehensive methodology for high-quality photometry and population analysis of NGC 4214 using multi-filter HST observations.

Findings

Detection of both young and old stellar populations

Resolved stellar populations at 2.94 Mpc distance

Methodology for transforming photometry into physical parameters

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 HST/WFPC2+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 (2.94 Mpc) and we perform a general description of those populations.
