ADC_Keywords: Active gal. nuclei ; Galaxies, Seyfert ; Photometry ; Spectroscopy ; Optical ; X-ray sources ; Ultraviolet Keywords: galaxies: active - galaxies: Seyfert - quasars: general - quasars: supermassive black holes Abstract: We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured (N_H<1022cm-2) active galactic nuclei (AGN) in the local Universe. Using a representative sample of hard-X-ray-selected AGN from the 70-month Swift/BAT catalog, with optical/UV photometric data from Swift/UVOT and X-ray spectral data from Swift/XRT, we constructed broadband SEDs of 236 nearby AGN (0.001<z<0.3). We employed GALFIT to estimate host galaxy with a reflection component to model the X-ray spectra and a dust-reddened multi-temperature blackbody to fit the optical/UV SED. We calculated intrinsic luminosities at multiple wavelengths, total bolometric luminosities (Lbol), optical-to-X-ray spectral indices (αox), and multiple bolometric corrections (κλ) in the optical, UV, and X-rays. We used black hole masses obtained by reverberation mapping and the virial method to estimate Eddington ratios (λEdd) for all our AGN. We confirm the tight correlation (scatter=0.45dex) between UV (2500Å) and X-ray (2keV) luminosity for our sample. We observe a significant decrease in αox with Lbol and λEdd, suggesting that brighter sources emit more UV photons per X-rays. We report a second-order regression relation (scatter=0.15dex) between the 2-10keV bolometric correction (κ2-10) and αox, which is useful to compute Lbol in the absence of multiband SEDs. We also investigate the dependence of optical/UV bolometric corrections on the physical properties of AGN and obtain a significant increase in the UV bolometric corrections (κW2 and κM2) with Lbol and λEdd, unlike those in the optical (κV and κB), which are constant across five orders of L_bol and λEdd. We obtain significant dispersions (∼0.1-1dex) in all bolometric corrections, and hence recommend using appropriate relations with observed quantities while including the reported scatter, instead of their median values. Description: In this paper, we present one of the largest studies to date of optical-to-X-ray wavelength SEDs for a sample of 236 unobscured, hard-X-ray-selected, nearby AGN from the 70-month Swift/BAT catalog. We compiled simultaneous optical, UV, and X-ray observations for all sources to mitigate any issues arising due to differences in the variability timescales at different wavelengths. We extracted the 0.3-10keV X-ray spectra and magnitudes and fluxes in the six Swift/UVOT filters: V, B, U, UVW1, UVM2, and UVW2 for all our sources. We corrected the optical/ UV fluxes for galactic dust extinction as well as host galaxy contamination. The latter was done by fitting the 2D surface brightness of the source images using a PSF and a Sersic profile with GALFIT to fit the AGN and the host galaxy, respectively. We also performed numerous simulations by creating fake populations of type I AGN and fitting them using GALFIT, to quantitatively inspect the reliability of the AGN magnitudes calculated by GALFIT. As a result of these simulations, we were able to calculate correction factors in each of the six Swift/UVOT filters, which can be used to correct the GALFIT-estimated PSF fluxes. We constructed and fit the multiwavelength AGN SEDs (10-7 to 500keV) using a dust-reddened multi-temperature blackbody to model the optical/UV accretion disk and a variety of X-ray models consisting of multiple components to account for the primary X-ray emission and the reprocessed secondary emission.
