What does Overtall Efficiency (Vapor Density) in FRI Dualflow mean, and what is its function?

I have been using the cross-flow tower module in FRI for design work recently, and I noticed that the calculation results include two types of efficiency values: Overtall Efficiency (Two Film) and Overtall Efficiency (Vapor Density). I had never heard of Overtall Efficiency (Vapor Density) before, and I’m not sure what it is used for. Could some expert please explain it to me?

OVERALL EFFICIENCY(TWO FILM)(Overall tower efficiency, based on the dual-film theory) OVERALL EFFICIENCY(VAPOR DENSITY))(Overall tower efficiency, using the gas density approach) Copied from elsewhere: lol
