Difference in the SFRs of paired galaxies with respect to the unpaired control sample vs. the pair separation scaled by the virial radius of the pair. Left: pairs with stellar mass ratios below 1/3. Primaries correspond to the more massive galaxy in a pair and are denoted by blue squares, while secondaries (the less massive in a pair) are denoted by red circles. Blue and red lines correspond to the running means for primaries and secondaries, respectively, with 1σ errors on the means denoted as shaded regions. Horizontal dashed and dotted black lines denote the 1σ and 2σ scatter of unpaired galaxies. Right: pairs with stellar mass ratios above 1/3. The notation is the same as in the left panel, except that the running mean (black line) is calculated by taking primary and secondary galaxies together.
