Summary0001231: Wrong calculation in wideBandAbsorptionEmission::addIntensity
DescriptionWhen calculating total incident radiation G, the value is too low when more than one band is used. This is caused by wideBandAbsorptionEmission::addIntensity, line 303, which states:

return ILambda*(iBands_[i][1] - iBands_[i][0])/totalWaveLength_;

ILambda is passed as a parameter from radiativeIntensityRay as ILambda_[lambdaI]. Since ILambda_[lambdaI] contains 100% (not more, not less) of the radiation in that ray direction in that band, there is no need for applying a weight-by-band factor. Instead:

return ILambda;

produces the expected result. This makes wideBandAbsorptionEmission::addIntensity obsolete, since this is already the behavior of absorptionEmissionModel::addIntensity . Consequently, absorptionEmissionModel::addIntensity may not be necessary at all.
