PG_q_fun: Gives values for the Plant Growth BSWF as a function of wavelength
Description
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
PG_q_fun(w.length)
Value
a numeric array of the same length as w.length with values for
the BSWF normalized as in the original source (300 nm)
