Jonas:
I seem to remember that the 4th power thing is due to (largely due to?)
the strongly rising "center" of the frequency as temperature increases.
Thus, the radiated power through a narrow window (visible band is only 1
octave) is probably only proportional to the /first/ power, at least
when that window is well below the peak power frequency.
If true, any error contributed by that window rapidly becomes
unimportant as temperature increases.

glows in the visible range due to transmissivity in the visible range. The

6) It is therefore wrong to use Stefan–Boltzmann without prior
calibration for the difference, which can be substantial
