These analogs share the same location of the UV-selected star-forming galaxies at $z\\sim2$ on the [OIII]/H$\\beta$ versus [NII]/H$\\alpha$ nebular emission-line diagnostic (or BPT) diagram. Their physical properties closely resemble those in $z\\sim2$ UV-selected star-forming galaxies being characterized in particular by high ionization parameters ($\\log q\\approx7.9$) and high electron densities ($n_e\\approx100~\\rm{cm}^{-3}$).
