Yay for more Ringworld! Nice image.

I don't remember any of the details any more, but I remember spending time going
through the book for measurements and descriptions when I last tried this (some
years ago now), and I don't recall any issues like you describe. Someone
mentioned ambient in the foregoing discussion - of course, the lit areas of the
Ring would cast secondary light onto the night areas. I'm sure Niven mentioned
arch-light in place of moonlight somewhere...

And of course his maths was bad - he had to write an entire sequel novel just to
deal with the Ringworld's intrinsic instability ;-)
