Catalog and Atlas from a Sensitive 1.5 GHz Radio Survey Around the North Ecliptic Pole

Abstract

A 29.3 square degree region surrounding the North Ecliptic Pole (NEP) is mapped with the Very Large Array (VLA) at 1.5 GH to support the deepest portion of the ROSAT all-sky soft X-ray survey. A total of 114 fields were mapped, and radio sources with peak brightnesses exceeding approx. 6 times the field's root-mean-square noise were identified. The resulting VLA-NEP survey catalog contains 2435 radio sources with flux densities in the range of 0.3 - 1000 mJy, including over 200 fainter than 1 mJy. We present here (1) the VLA-NEP survey catalog, (2) suggested counterparts for approx. 18% of the VLA-NEP objects, and (3) all-atlas of an 114 survey fields with catalogued sources indicated. In an Appendix we present initial scientific analysis of the VLA-NEP survey. The catalog and related tables are available electronically.
