The Origin of Double-peaked Narrow Lines in Active Galactic Nuclei II:
  Kinematic Classifications for the Population at z < 0.1
  We present optical longslit observations of the complete sample of 71 Type 2
active galactic nuclei (AGNs) with double-peaked narrow emission lines at $z <
0.1$ in the Sloan Digital Sky Survey. Double-peaked emission lines are produced
by a variety of mechanisms including disk rotation, kpc-scale dual AGNs, and
NLR kinematics (outflows or inflows). We develop a novel kinematic
classification technique to determine the nature of these objects using
longslit spectroscopy alone. We determine that 86% of the double-peaked
profiles are produced by moderate luminosity AGN outflows, 6% are produced by
rotation, and 8% are ambiguous. While we are unable to directly identify dual
AGNs with longslit data alone, we explore their potential kinematic
classifications with this method. We also find a positive correlation between
the narrow-line region (NLR) size and luminosity of the AGN NLRs
(R$_{\mathrm{NLR}}\propto \; {\mathrm{L}_{\mathrm{[OIII]}}}^{0.21 \pm 0.05}$),
indicating a clumpy two-zone ionization model for the NLR.
