# Generalized plant action spectrum 

# Action spectrum suggested by:
# M.M. Caldwell,
# "Solar UV irradiation and the growth and development of higher plants",
# In: Photophysiology, edited by A.C. Giese, Volume 6, Chapter 4, 
# pp. 131 - 177, 1971

# Spectrum was parameterized based on Equation (24) in:
# A.E.S. Green, T. Sawada, and E.P. Shettle,
# "The middle ultraviolet reaching the ground",
# Photochemistry and Photobiology, Vol 19., pp. 251-259, 1974:

# A = 2.618*(1-(w/313.3)^2)*exp((300-w)/31.08)
# w is wavelength in nm.

# NOTE: Caldwell 1971 defines the action spectrum as "relative photon 
# effectiveness".  The spectrum is used "as is", without converting
# it to energy units. 

# Dose rates derived with this action spectrum are part of NSF UV database 3 
# and are labeled "Caldwell".

# Integration range: 286 - 313 nm
