The Exploration of Local VolumE Satellites (ELVES) Survey: A Nearly
  Volume-Limited Sample of Nearby Dwarf Satellite Systems
  We present the final results of the Exploration of Local VolumE Satellites
(ELVES) Survey, a survey of the dwarf satellites of a nearly volume-limited
sample of Milky Way (MW)-like hosts in the Local Volume. Hosts are selected
simply via a cut in luminosity ($M_{K_s}<-22.1$ mag) and distance ($D<12$ Mpc).
We have cataloged the satellites of 25 of the 31 such hosts, with another five
taken from the literature. All hosts are surveyed out to at least 150 projected
kpc ($\sim R_\mathrm{vir}/2$) with the majority surveyed to 300 kpc ($\sim
R_\mathrm{vir}$). Satellites are detected using a consistent semi-automated
algorithm specialized for low surface brightness dwarfs. As shown through
extensive tests with injected galaxies, the catalogs are complete to
$M_V\sim-9$ mag and $\mu_{0,V}\sim26.5$ mag arcsec$^{-2}$. Candidates are
confirmed to be real satellites through distance measurements including
redshift, tip of the red giant branch, and surface brightness fluctuations.
Across all 30 surveyed hosts, there are 338 confirmed satellites with a further
105 candidates awaiting distance measurement. For the vast majority of these,
we provide consistent multi-band S\'{e}rsic photometry. We show that satellite
abundance correlates with host mass, with the MW being quite typical amongst
comparable systems, and that satellite quenched fraction rises steeply with
decreasing satellite mass, mirroring the quenched fraction for the MW and M31.
The ELVES survey represents a massive increase in the statistics of surveyed
systems with known completeness, and the provided catalogs are a unique dataset
to explore various aspects of small-scale structure and dwarf galaxy evolution.
