Examples of different triplet emission (indicated by the vertical dashed line) among particular types phenomena. Triplet emission for Type 1 is very distinct, with clear similarity to Mg II h and k line, emission appears also in triplet line center, but still we observe central absorption. The middle panel presents triplet emission for Type 2 CBs with strong emission in wings (sometimes even stronger than in the Mg II h and k line). This type of emission appears also in Type 3 (right panel). Below profiles we are showing corresponding spectra.
