摘要
Galaxies with delta greater than or equal to -45 degrees and \b\ greater than or equal to 10 degrees in the IRAS Bright Galaxy Sample, Part II, were observed at 1.425 GHz by the Very Large Array in its B, CnB, C, DnC, and D configurations. An atlas of radio contour maps and a table listing the principal radio source parameters (position, flux density, angular size) are given. This atlas of 187 galaxies supplements the 1.49 GHz atlas of 313 galaxies in the revised Bright Galaxy Sample, Part I. Together, they are complete for extragalactic sources stronger than S = 5.24 Jy at lambda = 60 mu m in the area \b\ > 10 degrees, delta > -45 degrees. To the extent that the far-infrared and radio brightness distributions overlap, these radio maps provide the most accurate positions and high-resolution images of the brightest extragalactic far-infrared sources.
