The 'classical' action spectra of K. J. McCree (1972) for Amaranthus edulis Speg. var. UCD 1966 and Avena sativa L. var. Coronado are included in this data set. Response is net CO2 uptake measured of leaf sections. Light source was a xenon-arc lamp fitted with a monochromator. Irradiance was in the range 10 to 15 W m$^-2$.
A response_mspct object with two member response_spct
