A revised machine-readable source list for the Rees 38-MHz survey. ... 233R ============================================================================ We present a revised machine-readable source list for the Rees 38-MHz (or '8C') survey with improved positions and no redundancy. The Rees 38-MHz survey covers an area of about 1 sr north of declination +60 degrees. The angular resolution is 4.5 x 4.5cosec(dec) arcmin**2 and the limiting flux density over much of the survey area is about 1 Jy. ...
