UVB: Constructor of ultraviolet-B waveband

Description

Wavelength-range definitions for ultraviolet-B, UV-B radiation, by default according to ISO or as commonly used in different application areas.

Usage

UVB(std = "ISO")

Value

a waveband object defining a wavelength range.

Arguments

std

a character string "CIE", "ISO", "medical" or "none"

Details

Implemented definitions. UV-B according to CIE and ISO standrads: 280--315 nm. UV-B according to common non-standard practice: 280--320 nm. UV-B according to medical or dermatological non-standard practice: 280--320 nm.
