Notes.t0: age of the oldest stars that contribute to the SED; τ: e-folding time of the exponential part of the SFH; ttrunc: age of the truncation/burst episode; SFR ratio: ratio of SFR after and before the truncation/burst episode; E(B − V): color excess of the nebular lines and of the stellar continuum. Other SED parameters are fixed.
