SED of GRB 130528A host galaxy in the B,r,i,z,J, and K_S bands. The AB magnitudes are corrected considering for the Galactic extinction E(B − V) = 0.144 (Schlafly & Finkbeiner 2011). The thick line shows the best fit (χ²/d.o.f. = 0.564) achieved with A_V = 0, a stellar population with an age of 2.6 Gyr, M_B = −21.16, and Solar metallicity. The rest of the lines show the evolution of the SED fit when A_V increases gradually from 0 to 0.8. As seen, the fit gets worse when A_V grows.
