Comparison of SFR evaluated from the extinction-corrected Hα line flux and the SFR based on the total IR luminosity obtained from the SED fit. The triple-dot-dash line corresponds to the relation with slope m = 1. The dot-dashed line corresponds to the linear fit of the data. (m = 0.8 ± 0.02 and m = 0.74 ± 0.06 for A983 and A1731, respectively). The left and right panels refer to A983 and 1731, respectively.
