Examples of nonbarred lens galaxies. (a, c) show the images, whereas (b, d) show the 2-dimensional surface brightness profiles, in which overplotted are the fitted functions to the structural decompositions, as well as the total model. White dots are for the image pixel values, and the black lines/dots are for the total model. Models for the bulges are shown by dark grey lines and the models for the lenses by light grey and black dots in the inner regions. For example, in NGC 524 the two curved inner components are the nuclear lens (nl) and lens (l), and the outer exponential function fits the outer lens (L). This figure was originally published by Laurikainen et al. [25].
