Illustration of the two methods used for defining the regions for the measurements of the component colors. In the left panel the r-band image of NGC 4245 is shown. In the middle panel we show the automatically defined regions for the central region (“nuc1” and “nuc2”; light and dark blue, respectively), for the barlens (“blc”; red), the bar (green), and the disk (yellow), see the text for details. In the right panel the manually selected regions for the barlens, the bar and the disk are shown (central regions are the same as in the middle panel). All images are in the same scale.
