This is my coordinate system: http://www.infoboard.org/screenshots/system.png
P_a can be any point on the vertical gray line and P_b can be any of the orange points on the outer radius (atmosphere).
The inner circle is the Earth and has an radius of 6 000 000 meters and the outer radius is...
Hello!
I am working on atmospheric scattering and therefore I have to calculate the optical depth along a given path through the atmosphere.
The integral I have to solve is this one:
\int_{P_a}^{P_b} f ds \quad with \quad f:R\rightarrow R, h\rightarrow e^{(-h/H_0)}
P_a und P_b are...
