The calculation for how the greenhouse pressure influences temperature is easy enough, but there's absolutely no mention of the anti-greenhouse pressure. Is it factored into the same equation or is it a completely separate modifier?
I'm asking because I'm in the following situation: There's a planet in a system adjacent to Sol that would make a perfect spot to locate a long term sector command. The furthest system from the new location that I'm looking at colonizing would require a radius of five and contains ruins and a nearly habitable world (0.67 colony cost), but there are closer systems that are highly useful as well and I don't want to build half a dozen smaller sector commands to cover all of the systems.
The problem? Said planet is sitting on a colony cost of 24.31, a surface temp of 578C, and a pressure of 14.2, of which is 98% carbon dioxide. In other words, were it not for the 3.0 cap on the greenhouse effect, I'd be looking at a value of over 16. This is why I'm asking the original question. If the AGG is a separate modifier, I'd be able to get the colony cost down to a more reasonable level quickly and start shipping colonists within a few years. If it's included in the original equation, ie before the artificial cap is put into place, I'm pretty much frakked on the terraforming front and will have to divert industry to produce orbital habitats, if I decide to go through with the plan at all.
