The IRAS Revised Bright Galaxy Sample (RBGS) comprises galaxies and unresolved mergers stronger than S=5.24 Jy at lambda=60 mu m with galactic latitudes vertical bar b vertical bar > 5 degrees. Nearly all are dusty star-forming galaxies whose radio continuum and far-infrared luminosities are proportional to their current rates of star formation. We used the MeerKAT array of 64 dishes to make 5 x 3 min snapshot observations at nu = 1.28 GHz covering all 298 southern (J2000 delta < 0 degrees) RBGS sources identified with external galaxies. The resulting images have theta approximate to 7'''.5 arcsec FHWM resolution and rms fluctuations sigma approximate to 20 mu Jy beam(-1)approximate to 0.26 K low enough to reveal even faint disk emission. The rms position uncertainties are sigma(alpha) approximate to sigma(delta) approximate to 1 '' arcsec relative to accurate near-infrared positions, and the image dynamic ranges are DR greater than or similar to 10(4):1. Cropped MeerKAT images of all 298 southern RBGS sources are available in FITS format from 10.48479/dnt7-6q05.
