# Stripe 82 1.4 GHz VLA Snapshot Survey Radio Source Component Catalogue.

This product contains the radio source component sample from Heywood et al. 2016. (http://adsabs.harvard.edu/abs/2016MNRAS.460.4433H)

The Very Large Array has been used to image ~100 deg2 of SDSS Stripe 82 at 1-2 GHz. The survey consists of 1026 snapshot observations
of 2.5 min duration, using the hybrid CnB configuration. The catalogue
produced using PyBDSF for this survey contains 11 782 point and Gaussian components.

The catalogue of optical counterparts of this survey can be found in dmu13 and described in Prescott et al. 2018. (https://arxiv.org/abs/1806.10140)

The catalogue will be available on dropbox.
