Yes I have, see attached. But perhaps you should keep current rather than relying on a distorted look at a 1973 study. Notice in the original published study, the term for the curve is relative.
There is a source that is very credible. It is a textbook in its 6th edition where the authors have published some more recent peer reviewed studies on the topic of absorption, action, and quantum yield. Quantum yield has been misused by the grow light charlatans. Quantum yield and action cannot take place if they are not absorbed. The quantum yield chart is relative to those photons that have been absorbed. What is much clearer and more difficult to distort is an absolute chart. The broad spectrum charlatans like to use the very old 1973 McCree chart because it is easy to misconstrue.
It may help to understand the subject. It's not just a graph, there is a lot going on as far as how the photons are used. Tossing the name McCree does not mean a damn thing. This is a simple question from the textbook referenced below. If you can't answer this then what you say is not relevant. Explain the concept of quantum yield. Compare and contrast the quantum yields of photochemistry, oxygen evolution, and photosynthetic carbon fixation. Explain the differences between the respective quantum yield values.
The McCree study still holds today, I am not trying to discredit McCree. I find it just pathetic how the charlatans distort his findings.
But a more modern look at absorbance and action chart like from a 2014 6th edition authoritative textbook which contains all the references to the peer reviewed studies to back its contents, may paint a more accurate picture.
Below is the absorbance and action chart (with citations) for the textbook Plant Physiology and Development. It is a $168 text book that has survived in a very tough market to make it to a 6th edition with a price tag like that.
