Centigrade/Kelvin symbol in LaTeX

[compilerbitch]

Does anyone here happen to know how to set a centigrade/kelvin symbol in LaTeX (raised small circle). I could hack about with math symbols to do it, but most fonts have proper glyphs for this and I'd prefer to use the real thing. Any clues? I've drawn a blank with my usual sources.

Sure, drop it to me in an email and I'll have a look at it.

Thanks! I will be happy to reward you with nice dinner for this!

(Relevant stuff is in Chapter 2, at least what there is of it so far)

All looks fine to me, except possibly one thing. What do you mean by a "black body facing away from the sun", exactly?

That bit came from some fairly obscure digging I did to figure out what temperatures satellites actually are subjected to. The idea is that if you have a perfectly black (fully absorbing regardless of wavelength) thingummy with line of sight to the sun, it will reach (what was it? 7C or something?), but in shadow, it would get extremely cold. I probably need to rephrase that section.
