Abstract:The VLA has been used in its most compact D- and C/D-configurations to make low-resolution ({theta}~0.9FWHM) 1.49GHz maps of the spiral galaxies north of DE=-45{deg} and brighter than B_T_=+12, the completeness limit of the Revised Shapley-Ames Catalog (Cat. VII/51). Most of these maps are confusion-limited at {sigma}>=0.1mJy per beam, and at least 94% of the galaxies were detected with S>=1mJy. The maps have sufficient sensitivity to low-brightness emission that accurate radio "photometry" is possible. An atlas of contour maps, a table of total flux densities plus other radio source parameters, and references to published radio maps are given.
