Caption: Figure 3.
Same as Figure 2 but for OBS-32 (SO 490, upper row) and OBS-93 (ISO-ChaI-143, lower row). Both are classified as DBC (S + BC–like), indicating that the BC dominates while part of the spectrum may arise from shock-origin emission. Although the upper-row example (OBS-32; SO 490) appears consistent with this interpretation, this interpretation is unlikely for the lower-row example (OBS-93; ISO-ChaI-143), because the fitting fails to reproduce the double-peaked Hβ profile.
