Locations of high- and low-metallicity regions of galaxies with azimuthal abundance asymmetry in the N/O – O/H diagram. The circles designate the (O/H)h regions in the moderate-mass galaxies, and the plus signs show the (O/H)l regions in these galaxies. The squares denote the (O/H)h regions in the massive galaxy M-11761-12705, and the crosses mark the (O/H)l regions in this galaxy. The yellow points show H II regions in nearby galaxies (compilation in Pilyugin & Grebel 2016).
