Atmospheric composition (expressed as the molar fraction of each gas in the atmosphere) for exoplanets from 0.1 to 6 Earth masses (M_E, columns) and an MO mass from 0.1 to 1 times the planetary silicate mass (Φ, rows) for all three $f_{{\mathrm{O}}_2,\mathrm{e}\mathrm{q}}$, investigated (expressed as ΔIW). The numbers indicate the total surface pressure in bar (the number in parentheses indicates the total surface pressure for cases without graphite precipitation). All cases have bulk silicate-equivalent abundances of 100 ppm of H, C, N, and S. The amount of some species (e.g., NH₃, HCN, SH₂, or S₂) is always too small to be noticeable in these charts.
