Overview of the Near-IR S0 Galaxy Survey (NIRS0S)

Figure 1

An example of the atlas image [25]. Figure (a) shows the whole galaxy using the full magnitude range, for which the scale is indicated in the right. The scales in x- and y-axes are in arcseconds. The small subfigures show the same image, but selecting the radial and magnitude scales in a different manner: (b) and (c) use the full radial scale, whereas in (d) only the central region of the galaxy is shown. The morphological classification is from the Atlas paper. The arrow indicates the barlens. The graphics show (e) the radial profile of the surface brightness, (f) ellipticity, (g) position angle, and (h) parameter b4, indicating deviations from perfect ellipticity. The logarithmic radial scale is in arcseconds. In these plots the vertical dashed lines indicate the bar radius, and the full line is the radius where the surface brightness is 20 mag arcseconds−2. The ellipse in figure (b) corresponds to the 2MASS K_20 isophote. Originally the figure appeared in Laurikainen et al. [25].
