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. ...

... Wind Baffle Parameters . ... As part of this analysis, the volume, mass, center of gravity and mass moment of inertia of the telescope and optics support structure (OSS) were computed. ... The total moment of inertia of the circular floor panel, wind baffle and telescope in azimuth should be correct to 30% but is dependent on estimates of the mass of equipment supported below and above the circular floor panel. ... Table 8 : Masses and mass moments of inertia of the wind baffle components. ...
