Comparison of stellar masses from the host sample of SGL09. The plot shows host masses derived from the photometry compiled in SGL09 and following Sect. 4.4.2 with models from Bruzual & Charlot (2003) against values directly taken from SGL09. Error bars are the maximum and minimum values of the stellar mass in the global χ²-distribution of 3 × 10⁶ galaxy templates (see Sect. 4.4.2). The solid lines represents equality, and the dashed line the median offset. Increasingly gray shaded areas indicate dispersions of 0.2, 0.5, and 1.0 dex, respectively. The inset shows the distribution of mass differences, which has a median of around 0.2 dex.
