      <description>This survey is a deep, high resolution radio survey of a relatively small region that has particularly deep coverage
in the Sloan Digital Sky Survey.  As described in the reference abstract:
This is a high-resolution radio survey of the Sloan Digital Sky Survey (SDSS) Southern Equatorial
Stripe, a.k.a., Stripe 82. This 1.4 GHz survey was conducted from 2007 to 2009 with the Very Large Array primarily in the A-configuration,
with supplemental B-configuration data to increase sensitivity to extended structure.
The survey has an angular resolution of 1.8" and achieves a median rms noise of 53 microJy/beam over 92 square degrees.  
This is the deepest 1.4 GHz survey to achieve this large of an area filling in the 
phase space between small&amp;amp;deep and large&amp;amp;shallow surveys.  
&lt;p&gt;
The astrometric accuracy of the data is excellent with errors in observed sources of 0.10" in both RA and declination.  
A comparison with the SDSS DR7 Quasar Catalog confirms that the astrometry is well tied to the optical reference 
frame with mean offsets of 0.02+/-0.01" in RA and 0.01+/-0.02 in declination.  Provenance:  TBD. This is a service of NASA HEASARC.
