alphaopic.action.spectra: Alphaopic (+ photopic) action spectra

In LightLogR: Process Data from Wearable Light Loggers and Optical Radiation Dosimeters

Alphaopic (+ photopic) action spectra

Description

A dataframe of alphaopic action spectra plus the photopic action spectrum. The alphaopic action spectra are according to the CIE S 026/E:2018 standard. The alphaopic action spectra are for a 32-year-old standard observer. The photopic action spectrum is for a 2° standard observer.
