Caption: Figure 2.

The effect of [O III] and Hβ lines on the Hα flux estimated from our HST data is shown in the right panel; the effect of the two [N II] lines in the top one (see text for details). The largest panel shows the range of [O III]/Hβ and [N II]/Hα line ratios using as a reference the Baldwin–Phillips–Terlevich (BPT) diagram obtained from MUSE observations of JO204 (Gullieuszik et al. 2017).
