Abstract:
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, 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. We present the
catalog containing the properties of galaxies observed by the wings
spectroscopic survey, which were derived using stellar populations
synthesis modelling approach. We also check the consistency of our
results with other data in the literature. 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. ∼5300 spectra were
analyzed with spectrophotometric techniques, and this allowed to
derive the star formation history, stellar masses and ages, and
extinction for the wings spectroscopic sample that we present in this
paper. 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.
Description:
Total stellar mass, stellar mass as a function of age, luminosity- and
mass-weighted ages, and dust extinction values are presented for 5299
galaxies in 48 nearby galaxy clusters. Galaxies in the following
clusters have been observed: A1069, A119, A151, A160, A193, A1291,
A1631a, A1644, A1795, A1831, A1983, A1991, A2107, A2124, A2169, A2382,
A2399, A2415, A2457, A2572a, A2589, A2593, A2622, A2626, A3128, A3158,
A3266, A3376, A3395, A3490, A3497, A3556, A3560, A376, A3809, A500,
A671, A754, A957x, A970, IIZw108, MKW3s,RX0058, RX1022, RX1740, Z2844,
Z8338, and Z8852. Together with the afore mentioned parameters, we
also provide model-derived observed and absolute magnitudes in Johnson
and SLOAN photometric systems.

Note (1):
Definitions of stellar masses:
* 1: the initial mass of the Single Stellar Population (SSP),
at age zero; this is nothing but the mass of gas turned into stars
* 2: the mass locked into stars, both those which are still in the
nuclear-burning phase, and remnants such as white dwarfs,
neutron stars and stellar black holes
* 3: the mass of stars that are still shining, i.e. in a
nuclear-burning phase.
The age bins are: 1: 0-20Myr; 2: 20-600Myr; 3: 0.6-5.6Gyr; 4: >5.6Gyr
