Distribution of the spaxels of our sample of galaxy pairs shown in an [OIII]/Hβ and [NII]/Hα diagnostic diagram. The solid and dotted black lines are the star-forming and composite classification lines, respectively, defined in Kewley et al. (2006). The red and yellow contours represent the distribution of spaxels with Hα equivalent width greater than or less than 6 Å, respectively.
