Galaxy Atlas

For each galaxy image five images/plots are shown. In the upper left corner, if available, a colour image of the galaxy is shown, taken from the Sloan Digital Sky Survey¹².
In the upper right corner (or center) a contour map of the respective galaxy is shown. The contour lines are set in equidistant intervals of 0.5 magnitude with the value of the outermost isophote, $\mu_{\textrm{\scriptsize lim}}$, given in the upper right corner. The contour maps of FGC 2339, IC 5249 and NGC 4179 originate from Pohlen (2000) and Pohlen et al. (2004).
In the second row a set of vertical profiles next to a set of radial profiles of the complete galaxy are shown. For each profile three cuts are selected. Errorbars are not shown to keep the quality of the plot. The horizontal cyan line represents $\mu_\textrm{\scriptsize crit}$ (see Section 2.4.2 and Table 8), i.e. the surface brightness up to where we trust the profile.
On the last row a four window set of plots of vertical profiles are shown of the selected fit datapoints with their errors (black dots), the model fit (red line), the thin disk component to the fit (magenta line), the thick disk component to the fit (green line) and the single disk fit (blue line). The profiles have been chosen on their quality to clearly show thick disk component if present. For FGC 2339 and IC 5249, for which no two disk fit could be made, only the single disk fit is shown. For the galaxies not used for the fit no plots are shown.
