On colony size --

the default facility capacity is the following:

Size Breathable Non-breathable
---------------------------------------
Tiny 5 1
Small 10 2
Average 15 3
Large 20 4
Huge 25 5

with something like x1.2 for advanced storage techniques.

To take full advantage of a planet with a different atmosphere, you can...

a) Use Atmospheric Modification Plants, as noted before. IIRC, you need Biology, followed by Applied Planet Utilization, but check the TechArea.txt file. There are three levels of AMPs, if memory serves (at least in the demo), and they all take many turns to work, plus a decent amount of resources to build. So this might not be that good in the 100-turn demo.

b) IIRC, if you have assimilated another race that can breathe the atmosphere, and you use only colonists that can there, you may be able to use the full capacity.

*sigh* Ah, how many RPs would I give for terraforming satellites...

(particularly if they worked on hostile, occupied worlds ;-))
