Here are the answers to PS2.
The following assumptions have been made:
-Zenith angle = 45 deg;
-Only Rayleigh scattering and absorption by O3 and O2 are considered;
-O3 mixing ratio is averaged over each 5km slab;
-Both O3 and O2 column number density are based on the exact solution
for atmospheric column density;
-Attenuation of the solar flux above 50km by O2, Rayleigh scattering,
and O3(2.0e16).

These calculations are the same as the first ACCEPT that the O3
number density is averaged over each 5km slab.
