Acquisition rate for MPGs as a function of the different variables.

	T _e	N2	O3N2	R₂₃	Ne3O2	Ar3O3


Z¹	0.923	0.962	0.962	0.909	0.858	0.887
Z + Hα/Hβ²	0.915	0.960	0.960	0.925	0.881	0.909

Notes.

⁽¹⁾

Strong emission line ratios for each method plus redshift to identify MPGs.

⁽²⁾

Strong emission line ratios for each method plus redshift and (Hα/Hβ) to identify MPGs.
