Equation

in optcv.F90 :

TRAY(K,NW) = TAURAY(NW) * DPR(K)

TAURAY(NW) is calculated in calc_rayleigh.F90

TAURAY(NW) \[ \tau_{RAY} = \displaystyle \frac{\int \tau(\lambda) B_{\lambda} \, \mathrm{d}\lambda}{\int B_{\lambda} \, \mathrm{d}\lambda} \]

\( \displaystyle \tau(\lambda) \) is called TAUVAR
