Distribution of Hα/Hβ ratio for three different EW_Hα regimes. Each distribution represent the Hα/Hβ flux ratio for all bins between 6 Å < EW_Hα ≤ 10 Å (green), 3 Å < EW_Hα ≤6 Å (blue), and EW_Hα ≤3 Å (red), for the seven binned galaxies listed in Table 1. Black vertical dashed line presents the theoretical ratio of Hα/Hβ = 2.87 (Osterbrock & Ferland 2006). We can see that a substantial part of the bins with EW_Hα ≤ 3 Å shows a non-physical ratio (< 2.87).
