Emissivity εH2O of water vapor
at a total pressure of 1 bar as a function of temperature and the product pH2Oseq.

Correction factor f for water vapor (total pressure p ≤ 1 bar). For pressures p > 1 bar you must use Eq. (19)

Emissivity εCO2 of carbon dioxide at a total pressure of 1 bar as a function of temperature and the product pCO2seq.
Emissivity of ammonia

Emissivity of ammonia at a total pressure of 1 bar as a function of temperature and the product pNH3seq.
Emissivity of methane

Emissivity of methane at a total pressure of 1 bar as a function of temperature and the product pCH4seq.

Correction Δε for mixtures of carbon dioxide and water vapor at (a) 130°C, (b) 540°C, and (c) 920°C and above
Emissivity εSO2 of sulfur dioxide at a total pressure of 1 bar as a function of temperature and the product pSO2seq.
