Probing the Physics of Narrow Line Regions in Active Galaxies IV: Full
  data release of The Siding Spring Southern Seyfert Spectroscopic Snapshot
  Survey (S7)
  We present the second and final data release of the Siding Spring Southern
Seyfert Spectroscopic Snapshot Survey (S7). Data are presented for 63 new
galaxies not included in the first data release, and we provide 2D
emission-line fitting products for the full S7 sample of 131 galaxies. The S7
uses the WiFeS instrument on the ANU 2.3m telescope to obtain spectra with a
spectral resolution of R = 7000 in the red (540 - 700 nm) and R = 3000 in the
blue (350 - 570 nm), over an integral field of 25x38 arcsec^2 with 1x1 arcsec^2
spatial pixels. The S7 contains both the largest sample of active galaxies and
the highest spectral resolution of any comparable integral field survey to
date. The emission-line fitting products include line fluxes, velocities and
velocity dispersions across the WiFeS field of view, and an artificial neural
network has been used to determine the optimal number of Gaussian kinematic
components for emission-lines in each spaxel. Broad Balmer lines are subtracted
from the spectra of nuclear spatial pixels in Seyfert 1 galaxies before fitting
the narrow lines. We bin nuclear spectra and measure reddening-corrected
nuclear fluxes of strong narrow lines for each galaxy. The nuclear spectra are
classified on optical diagnostic diagrams, where the strength of the coronal
line [FeVII]6087 is shown to be correlated with [OIII]/Hbeta. Maps revealing
gas excitation and kinematics are included for the entire sample, and we
provide notes on the newly observed objects.
