The landing site will need to be in sunlight a significant amount of time due to the solar cells covering the lander, Philae. The red zones (100% sunlight) are apparently not favored, while the yellow and orange zones are. The green spots mark provisional landing sites. The blue zones are in permanent shadow.
Hey, thanks for that very interesting info and link!
Based on what you gave, I'm going to make an assessment that the said walled/crater-like structure in the lower-right image on Comet's body might actually correlate to the 'Orange' coordinates on the digitzed landing analysis graphic?
And orange oasis within a sea of 100% red no-go zone?
If so, my gut would still just say; go for that neat little sweet zone (even if it's not one of the provisionals)!
So of 10 remaining candidate landing sites (Sep 15), site "J" has been tentatively chosen, pending final review. It is on Chury's small lobe, and is near gas jets already forming (
S&T). I think I've located site J on the earlier graphic. The perspectives do not correlate exactly but close enough to show some similar features (in particular the permanent shadow zone):
