Top: morphological type distribution against SDSS r-band absolute magnitude distribution of the interacting sample. The number in each bin represents the sources included in it. Bottom: color magnitude diagram for the CALIFA MS, control and interacting samples. Morphologies and absolute magnitudes are taken from Walcher et al. (2014). Blue, yellow, pink, and red represent pre-merger, merger, post-merger, and merger remnants stages, respectively. Plus symbols represent the control sample. For comparison we plot the density contours of the CALIFA MS. Red and blue contours represent the early- and late-type galaxies. Each of the contours represents 25%, 50%, and 75% of the mother sample. Dotted vertical lines represent the range in absolute magnitudes where the CALIFA MS is representative of the overall galaxy population (Walcher et al. 2014).
