Abstract:
We present long-slit integrated spectroscopy of 238 late-type galaxies
belonging to the Herschel Reference Survey, a volume-limited sample
representative of the nearby universe. This sample has a unique legacy
value since it was ideally defined for any statistical study of the
multifrequency properties of galaxies spanning a wide range in
morphological type and luminosity. The spectroscopic observations
cover the spectral range 3600-6900Å at a resolution R~=1000 and are
thus suitable for separating both the underlying absorption from the
emission of the Hβ line and the two [NII] lines from the Hα
emission. We measured the fluxes and the equivalent widths of the
strongest emission lines ([OII]λ3727, Hβ,
[OIII]λ4959 and [OIII]λ5007, [NII]λ6548,
Hα, [NII]λ6584, [SII]λ6717, and
[SII]λ6731). We used the data to study the distribution of the
equivalent width of all the emission lines, of the Balmer decrement
C(Hβ), and of the observed underlying Balmer absorption under
Hβ (EWHβabs) in this sample. Combining these new
spectroscopic data with those available at other frequencies, we also
study the dependence of C(Hβ) and EWHβabs on
morphological type, stellar mass, stellar surface density, star
formation rate, birthrate parameter, and metallicity in galaxies
belonging to different environments (fields vs. Virgo cluster). The
distribution of the equivalent width of all the emission lines, of
C(Hβ) (or equivalently of A(Hα), and of EWHβabs
are systematically different in cluster and field galaxies. The Balmer
decrement increases with the stellar mass, stellar surface density,
metallicity, and star formation rate of the observed galaxies, while
it is unexpectedly almost independent of the column density of the
atomic and molecular gas. The dependence of C(Hβ) on stellar mass
is steeper than previously found in other works. The underlying Balmer
absorption does not significantly change with any of these physical
parameters.

Note (G2): Notes as follows:
a = spurious detections in the [OIII]4959 line in Gavazzi et al.
(2004, Cat. J/A+A/417/499)
b = new measurements on the original Gavazzi et al.
(2004, Cat. J/A+A/417/499) data
Note (G3): For consistency with our work, the original data of Kennicutt (1992,
Cat. VII/141) are corrected for the underlying Balmer absorption in
Hβ (5Å) and Hα (2.8Å).
The [OIII]4959 and the [NII]6548 equivalent widths are inferred from the
[OIII]5007 and the [NII]6584 measurements assuming a standard ratio
[OIII]5007/[OIII]4959=3 and [NII]6584/[NII]6548=3 (Osterbrock & Ferland,
2006, Astrophysics of gaseous nebulae and active galactic nuclei (Sausalito,
CA: University Science Book)). The [SII]6731 equivalent width includes the
emission of both [SII]6717 and [SII]6731 lines.
The original data of Jansen et al. (2000, Cat. J/ApJS/126/331) are corrected
only for the underlying Balmer absorption in Hα (2.8Å), but not for
that in Hβ given that the spectral resolution of these data, comparable
to our, allows the direct measurement of the underlying absorption.
The [OIII]4959 and the [NII]6548 equivalent widths of Moustakas et al. (2010,
Cat. J/ApJS/190/233) and Moustakas & Kennicutt (2006, Cat. J/ApJS/164/81)
are inferred from the [OIII]5007 and the [NII]6584 measurements assuming a
standard ratio [OIII]5007/[OIII]4959=3 and [NII]6584/[NII]6548=3
(Osterbrock & Ferland 2006, Astrophysics of gaseous nebulae and active
galactic nuclei (Sausalito, CA: University Science Book)).
In the original works of Moustakas et al. (2010, Cat. J/ApJS/190/233) and
Moustakas & Kennicutt (2006, Cat. J/ApJS/164/81) fluxes are absolute values
(not normalised) representative of the whole galaxies. The galaxy HRS 211 in
Moustakas et al. (2010, Cat. J/ApJS/190/233) is detected only in the Hbete
line.
