Irradiance of a area per device frequency or wavelength. The terms spectral flux density or maybe more confusingly "spectral intensity" also are employed. Non-SI models of spectral irradiance contain Jansky = ten W⋅m⋅Hz and solar flux device (1SFU = ten W⋅m⋅Hz). The Dean of Devices Hub retains the two https://guyh207bjq4.blogoscience.com/profile
