Abstract
The light distribution of a small sample of edge-on spiral galaxies is examined from optical to near-infrared wavelengths, in B, V, R, and I, by fitting model distributions to the light profiles. In general, the best fitting vertical model is more peaked than expected for an isothermal sheet distribution (sech2), i.e. it is either an exponential light distribution or a sech(z)-model. It is found that the vertical scale parameters for both the thin and the thick disks are confined within narrow ranges. The mean ratio of the radial to the vertical scale parameter in I, h r /z 0, is 5.9 ± 1.2.
