==== Case B2: Rayleigh scattering and molecular absorption ====

This test checks whether molecular absorption is correct. The setup is the same as for case B1 but with molecular absorption.

//Setup://

  * model atmosphere with 30 layers, scattering optical thicknesses provided in {{:intercomparisons:phase_b:tau_rayleigh.dat|}}, absorption optical thickness in {{:intercomparisons:phase_b:tau_molabs.dat|}} 
  * wavelength: 325 nm 
  * Rayleigh depolarization factor: 0.03
  * output altitudes: 0 km, 15 km, 30 km
  * sun position  (//sza//=60°, //saa//=0°)
  * viewing zenith angles: 
    * at 0 km : //vza//: 0° - 85°, 5° increment
    * at 15 km: //vza//: 0° - 180°, 5° increment (without 90°)
    * at 30 km: //vza//: 95° - 180°, 5° increment 
  * viewing azimuth angle //vaa//: 0° - 180°, 5° increment	     

//Output format://

  * The output should be provided in the same format as for case A1 ([[intercomparisons:a1_rayleigh|Rayleigh scattering]]).
