Description

Function to read the "response.type" attribute of an existing response_spct object.

Usage

Arguments

Details

Objects of class response_spct() can contain data for a response spectrum or an action spectrum. Response spectra are measured using the same photon (or energy) irradiance at each wavelength. Action spectra are derived from dose response curves at each wavelength, and responsivity at each wavelength is expressed as the reciprocal of the photon fluence required to obtain a fixed level of response.

Value

character string

Note

If x is not a response_spct object, NA is returned.
