Star formation rate in blue companion galaxies in solar masses per year. Left column shows SFR from from Hα-flux. Right column shows SFR calculated from [O ii]-flux. Three different redshift difference cuts are pictured for the pairs, top:  | Δz |  = 0.001, middle:  | Δz |  = 0.006, bottom:  | Δz |  = 0.012. Galaxies with SFR > 100 and individual errors in SFR_error > 1000 are excluded. The individual errors are unweighted in the calculations of mean values and error bars. Only objects with emission line fluxes that are greater than three times the error in the emission line flux are included.
