Descripción
Context. The WIde-field Nearby Galaxy clusters Survey (wings) is a
project whose primary goal is to study the galaxy populations in
clusters in the local universe (z < 0.07) and of the influence of
environment on their stellar populations. This survey has provided the
astronomical community with a high quality set of photometric and
spectroscopic data for 77 and 48 nearby galaxy clusters, respectively.
Aims: In this paper we present the catalog containing the
properties of galaxies observed by the wings SPEctroscopic (wings-spe)
survey, which were derived using stellar populations synthesis modelling
approach. We also check the consistency of our results with other data
in the literature. Methods: Using a spectrophotometric model that
reproduces the main features of observed spectra by summing the
theoretical spectra of simple stellar populations of different ages, we
derive the stellar masses, star formation histories, average age and
dust attenuation of galaxies in our sample. Results: ~ 5300
spectra were analyzed with spectrophotometric techniques, and this
allowed us to derive the star formation history, stellar masses and
ages, and extinction for the wings spectroscopic sample that we present
in this paper. Conclusions: The comparison with the total mass
values of the same galaxies derived by other authors based on sdss data,
confirms the reliability of the adopted methods and data.
Based on observations taken at the Anglo Australian Telescope (3.9 m-
AAT), and at the William Herschel Telescope (4.2 m- WHT).Full Table 2 is
