Surface photometry of low surface brightness galaxies 7 Table 1. ... 6) Total magnitude B 25 within 25 B­mag/ut 00 ellipse. ... The centers of the ellipses were usually determined by taking the maximum of the light dis­ tribution as the center. ... 3.2 Total magnitudes The total magnitude out to infinity mT , as defined by Equa­ tion (5), is a better estimate for the total luminosity of a LSB galaxy than the conventional m25 magnitude, which gives the amount of light within the 25 mag=ut 00 isophote. ...
