Abstract
For a complete sample of 120 northern galaxies with angular diameters 10 ≥ a ≥ 2 arc minutes and apparent aspect ratio a/b ≥ 7, CCD observations were carried out in the R'-passband. We present the isophotal images of the galaxies, their luminosity profiles and some basic photometric parameters. The isophotal aspect ratio for most flat galaxies turns out to be smaller than that given in catalogues and does not exceed (a/b)max = 15. We note a diversity of the galactic luminosity profiles and propose a classification based on the degree of deviation from the standard exponential law. About two-third of the flat galaxies have nonstandard profiles; however, this hardly can be attributed to strong internal absorption within edge-on galaxies.
