Abstract

Galaxy surface photometry with the Automated Photographic Measuring machine has been absolutely calibrated by comparison with photoelectric photometry and CCD images. In the range faintwards of 22.5 bj mag/sq arcsec J-mu, the photometry is consistent between images to 0.05 mag, has sky subtraction errors equal to or less than 0.2 per cent corresponding to 0.05 mag uncertainty at 26 J-mu, and has random photometric errors equal to or less than 1 per cent or 0.01 mag.
