Output spectrum

The output intensity $T_S$ and weight $w_S$ at channel $i$ are set to:
\textsf{Averaged channel intensity and weight (...
...{T'}(i)} \\
w_S(i) & = & w_{R'}(i) + w_{T'}(i)
where the $R'$ (resp. $T'$) index refers to the resampled version of input spectrum $R$ (resp. $T$) computed from eqs. [*] and [*]/[*]. The normalization in eq. [*] ensures that the integrated intensity is also preserved over the whole spectrum when averaging these two spectra. These equations are the same as eqs. [*]/[*] (for aligned spectra) except that they operate on their resampled versions.
