Visible (to humnas) radiation (380...760 nm) according to ISO standard definition, no weighting applied. For std = "RS" the returned range is the same as for PAR().

VIS(std = "ISO")

Arguments

std

a character string "ISO" or "RS" (remote sensing).

Value

A waveband object wavelength defining a wavelength range.
