Star-formation main sequence for the MAGMA sample as described in the text. The locus of the host galaxy for GRB 050709 is shown as a solid red square; the main sequence found by Saintonge et al. (2016) is shown as a dashed blue curve and the medians for MAGMA as heavy solid curves. The 050709 host falls within the range of normal star-forming galaxies, as shown by the gray regions that indicate a 1σ deviation from the MAGMA median.
