Red radiation according to "ISO" (610-760 nm) or as commonly defined in plant photobiology, "Smith10" (655-665 nm), "Smith20" (650-670 nm), "Inada" (600-700 nm), "Warrington" (625-675 nm), and "Sellaro" (620-680 nm). No weighting applied.
Red(std = "ISO")
a character string, defaults to "ISO".
a waveband object wavelength defining a wavelength range.
