The Stripe 82 1-2 GHz Very Large Array Snapshot Survey: Multiwavelength
  Counterparts
  We have combined spectrosopic and photometric data from the Sloan Digital Sky
Survey (SDSS) with $1.4$ GHz radio observations, conducted as part of the
Stripe 82 $1-2$ GHz Snapshot Survey using the Karl G. Jansky Very Large Array
(VLA), which covers $\sim100$ sq degrees, to a flux limit of 88 $\mu$Jy rms.
Cross-matching the $11\,768$ radio source components with optical data via
visual inspection results in a final sample of $4\,795$ cross-matched objects,
of which $1\,996$ have spectroscopic redshifts and $2\,799$ objects have
photometric redshifts. Three previously undiscovered Giant Radio Galaxies
(GRGs) were found during the cross-matching process, which would have been
missed using automated techniques. For the objects with spectroscopy we
separate radio-loud Active Galactic Nuclei (AGN) and star-forming galaxies
(SFGs) using three diagnostics and then further divide our radio-loud AGN into
the HERG and LERG populations. A control matched sample of HERGs and LERGs,
matched on stellar mass, redshift and radio luminosity, reveals that the host
galaxies of LERGs are redder and more concentrated than HERGs. By combining
with near-infrared data, we demonstrate that LERGs also follow a tight $K-z$
relationship. These results imply the LERG population are hosted by population
of massive, passively evolving early-type galaxies. We go on to show that
HERGs, LERGs, QSOs and star-forming galaxies in our sample all reside in
different regions of a WISE colour-colour diagram. This cross-matched sample
bridges the gap between previous `wide but shallow' and `deep but narrow'
samples and will be useful for a number of future investigations.
