Nikean Insolation

Insolation (from Latin insolare, to expose to the sun)^[1][2] is the total amount of solar radiation energy received on a given surface area during a given time. It is also called solar irradiation
- copied from Wikipedia.

"...in the upper air, he encountered severe turbulence. That was unexpected, on a planet that received less than 0.9 Terran...insolation..."
-Poul Anderson, Flandry's Legacy (New York, 2012), p. 469.

Poul Anderson's dictionary-necessitating vocabulary strikes again. I had guessed the meaning of "insolation" (not insulation) from the form of the word and also from the context, then Wikipedia confirmed it (see above). The three dots before "insolation" must indicate Roan Tom's hesitancy about applying a word derived from "Sol" to radiation from another star.

Like the recently spotted "acher," this is a word that I do not remember noticing on any previous reading. However, this time, I am rereading very carefully in order to find any possible detail to post about. I think that it has already been demonstrated that, the more deeply we look into Anderson's texts, the more there is to be found in them.
