Gives values for the CH4 production from pectin BSWF as a function of wavelength

Source: R/meth.e.fun.r
CH4_e_fun.Rd

This function gives a set of numeric multipliers that can be used as a weight to calculate effective doses and irradiances. The returned values are on quantum based effectiveness relative units.

Usage

CH4_e_fun(w.length)

Arguments

w.length

numeric array of wavelengths (nm)

Value

a numeric array of the same length as w.length with values for the BSWF normalized as in the original source (300 nm) and based on energy effectiveness.
