Figure A1. The singlefiber BPT diagrams of postmergers and control

Bpt Diagram. (a) BPT diagnostic diagram. Points are colorcoded Each of the three diagrams plots an [O III] line's ratio with H-β against another such ratio: [N II]'s ratio with Hα.[S II]'s ratio with Hα. The most famous version consists of [NII]6584/Ha versus [OIII]5007/Hb (the BPT-NII diagram; Fig

There is a significant shift in the placement of the NonSF decomposed spectra, as well as the emergence of two distinct clusters in the LINER and Seyfert regions The BPT diagrams are three types of diagram that plot the relative strengths of emission lines with the aim of determining the state of ionization of a plasma, specifically for classifying active galactic nuclei (AGNs)

Emission line diagnostic diagrams (a) BPT diagram purely

The emission-line diagnostic diagram, known as the BPT diagram, named after The N2-BPT diagram utilizing the line ratios of [OIII]λ5007/Hβ (hereafter O3) versus [NII]λ6584/Hα (hereafter N2) are regularly used as a tool to classify galaxies based on the dominant sources of ionizing radiation into categories such as star-forming. Both ratios are based on lines close in wavelength and are therefore nearly reddening independent
