Abstract:
We present a database of UV-to-FIR data of 83 nearby starburst
galaxies. The galaxies are selected based upon the availability of IUE
data. We have recalibrated the IUE UV spectra for these galaxies by
incorporating the most recent improvements. For 45 of these galaxies
we use observations by Storchi-Bergmann et al. (1995ApJS...98..103S 1995ApJS...98..103S)
and McQuade et al. (1995ApJS...97..331M 1995ApJS...97..331M) for the spectra in the
optical range. The NIR data are from new observations obtained at the
NASA/IRTF and the Mount Laguna Observatory, combined with the
published results from observations at the Kitt Peak National
Observatory. In addition, published calibrated ISO data are included
to provide mid-IR flux densities for some of the galaxies. The
optical-to-IR data are matched as closely as possible to the IUE large
aperture. In conjunction with IRAS and ISO FIR flux densities, all
these data form a set of observed spectral energy distributions (SEDs)
of the nuclear regions of nearby starburst galaxies. The SEDs should
be useful in studying star formation and dust/gas attenuation in
galaxies. We also present the magnitudes in the standard BVRI and
various HST/WFPC2 bandpasses synthesized from the UV and optical
wavelength ranges of these SEDs. For some of the galaxies, the
HST/WFPC2 magnitudes synthesized from the SEDs are checked with those
directly measured from WFPC2 images to test the photometric errors of
the optical data and their effective matching of apertures with the UV
data. The implications of the new SEDs on the star formation rates and
dust/gas attenuation are briefly discussed.

Note (1): Those of the non-mergers are from The Third Reference Catalogue
of Bright Galaxies (RC3; de Vaucouleurs et al., 1991, Cat. VII/155)
except that of Mkn789, which is from the NASA/IPAC Extragalactic
Database (NED); the references leading to the merger or pre-merger
classifications can be found in Keel & Wu (1995AJ....110..129K 1995AJ....110..129K).
Note (2): The values are from RC3 except for Mkn789 (from NED).
Note (3): From RC3 no correction for the Galactic extinction.
Photographic magnitudes are used if photoelectric magnitudes are
not available.
Note (4): From Bmag. Unless indicated otherwise, distances are from
Hubble's law (i.e., by ignoring the relativistic effects) with
recession velocities converted to those under the system used by
Sandage & Bedke (1988, Atlas of Galaxies Useful for Measuring the
Cosmological Distance Scale (NASA SP-496) (Washington: US GPO)),
except by dropping small non-linear terms in evaluating Virgo-infall
motion. The Hubble Constant is adopted as 65km/s/Mpc.

Note (1): The AB magnitudes given here can be transformed to the HST
STMAG systems by subtracting 2.38, 2.22, 1.98, and 1.62, for F170W,
F185W, F218W, and F255W, respectively. The magnitudes have been
corrected for the Galactic extinction with the
Schlegel-Finkbeiner-Davis system and CCM parameterization.
For table4.dat, in the integration, we include the contribution of the
optical spectra discussed in Section 3.2, which have certain effects
due to the small-valued yet largely extended wavelength ranges of the
filter throughput functions ("red leaks" most noticeable in the F170W
filter).
For table5.dat, there are no optical spectra available for these
galaxies to include the effects of "red leaks". Therefore, the
magnitudes may be systematically overestimated by 0.1 to 0.3 mag.
Note (2): There can be an additional systematic error of ∼0.03mag due
to the status of the MF recalibration. In some optical wavelength
ranges there are no spectra available and consequently these ranges
are missed in the integration. For the filter F170W the error caused
by this is expected to be ∼0.05mag for the galaxy NGC 1569, but
≤0.02mag for other galaxies. For the other three filters such
calculation errors are negligible, ≤0.01mag.
