Distribution of significant parameters for the sample. The pink histogram represents line-emitting sources, and the blue histogram portrays non-emitters. From top left to bottom right: stellar mass, average SFR over 10 Myr, attenuation, age of the most recent starburst, birth-cloud attenuation, interstellar medium attenuation, and IR luminosity. Each bar represents an equal probability (20%, except 33% for burst age).
