Planet Type in DA Custom Maps

I love the new Milky way map, however I want to add a degree of randomness to it so that its different every time I run it. I am basically writting a quick and dirty utility that will randomly create planets around the 220 stars on this map. The one part I am having trouble with is determining what the various TYPE values are. '0' I assume is normal, but im not sure what values are for toxic, radioactive, heavy etc.

Anybody have any insight on this? Seems I can't find a planet equivalent of StarTypes.xml

THanks in advance for any help.
