Comparison of our M_* values (derived from our MAGPHYS fits to data in GALEX, SDSS, and WISE filters) to those estimated using only WISE W1 and W2 photometry combined with the relations provided in CL14. The left panel shows the comparison to the relation for low-redshift sources, and the right panel shows the comparison to the relation for star-forming galaxies (see text). The typical error is shown in the bottom right corner of each panel. The coloured symbols show the morphology of the merging galaxies as described in the legend.
