Abstract:
We present a multifrequency dataset for an optically-selected,
volume-limited, complete sample of 118 late-type galaxies (≥S0a) in
the Virgo cluster. The database includes UV, visible, near-IR, mid-IR,
far-IR, radio continuum photometric data as well as spectroscopic data
of Hα, CO and HI lines, homogeneously reduced, obtained from our
own observations or compiled from the literature. Assuming the energy
balance between the absorbed stellar light and that radiated in the IR
by dust, we calibrate an empirical attenuation law suitable for
correcting photometric and spectroscopic data of normal galaxies. The
data, corrected for internal extinction, are used to construct the
spectral energy distribution (SED) of each individual galaxy, and
combined to trace the median SED of galaxies in various classes of
morphological type and luminosity.
Description:
The fitted spectral energy distribution (SED) of the templates:
