Abstract
To analyze the vertical structure of edge-on galaxies, we have used images
of a large uniform sample of flat galaxies that have been taken during the
2MASS all-sky survey. The photometric parameters, such as the radial scale
length, the vertical scale height, and the deprojected central surface
brightness of galactic disks have been obtained. We find a strong
correlation between the central surface brightness and the ratio of the
vertical scale height to the vertical scale length: the thinner the galaxy,
the lower the central surface brightness of its disk. The vertical scale
height does not increase systematically with the distance from the galaxy
center in the frames of this sample.
Key words: galaxies: structure -- galaxies: photometry
