Abstract:
The VLA has been used in its most compact D- and C/D-configurations
to make low-resolution (θ∼0.9FWHM) 1.49GHz maps of the spiral
galaxies north of DE=-45° and brighter than BT=+12, the
completeness limit of the Revised Shapley-Ames Catalog (Cat. VII/51).
Most of these maps are confusion-limited at σ≥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.
