- rayleigh(data, factor=1.0, model='nicolet')
- Compute Rayleigh molecular cross section and add extinction to optical depth(s) or absorption coefficient(s).
If a list of ac or od is given, add Rayleigh individually and return the corresponding list.
Optionally the extinction can be scaled by a "Rayleigh enhancement factor" (default 1.0).

- Earth atmosphere total optical depth.
