Blue: Constructor of blue waveband

Description

Wavelength-range definitions for blue light according to ISO or as commonly used in plant or remote sensing applications.

Usage

Blue(std = "ISO")

Value

A waveband object defining a wavelength range.

Arguments

std

a character string "ISO", "Sellaro", "Broad", "RS" (remote sensing), or Landsat imagers, "LandsatTM", "LandsatETM", or "LandsatOLI".

Details

The different arguments passed to formal parameter std determine the range of wavelengths set as boundaries of the returned waveband object; "ISO" is standardized definition based on human colour vision; "Sellaro" and "Broad" are non-standard but used in plant sciences; "RS" is non-standard but frequently used in remote sensing; the remaining definitions are for the published wavelength sensitivity range of imagers (cameras) in the Landsat satellite missions.
