Specific star formation rate SSFR(Hα) vs. the stellar mass M_∗ is shown by filled blue circles for LCGs (Izotov et al. 2011a). The location of HG 031203 is marked by the large red star. The dashed lines correspond from left to right to loci with SFR = 1, 10 and 100 M_⊙ yr^-1, respectively. Data from Svensson et al. (2010) are shown by large green open circles. Open green and purple stars show the position of HG 031203 from Svensson et al. (2010) and Watson et al. (2010), respectively. Data for different HGs from Levesque et al. (2010b) are shown by large filled light-blue squares with HG 031203 shown by a light-blue open star). (A colour version of this figure is available in the online journal.)
