... R c r P The flux density received at point P is: F = I cos d = I cos sin d d = 2I 0 c cos sin d = I sin2 c R2 = I ----r2 That is, we recover the inverse square law. ... F I d = size of circular aperture L Circular aperture L sec d d cos Projected aperture d cos d First calculate the solid angle of rays hitting P the back of the camera. ... Because of the delta-function, F = A B Hence, for an unresolved source, the flux per beam F source. is equal to the flux density of the 6. ...

... Printed in U.S.A. THE STELLAR DISK THICKNESS OF LOW SURFACE BRIGHTNESS GALAXIES D. Bizyaev 1,2,3 and S. Kajsin 4 Received 2003 October 23; accepted 2004 June 9 ABSTRACT We present surface photometry results for a sample of 11 edge-on galaxies observed with the 6 m telescope at the Special Astrophysical Observatory, Russia. ... We find from a comparison of photometric scales that the stellar disks of LSB galaxies are thinner than those of high surface brightness ( HSB) galaxies. ... UGC 11301 .. ...
