Looking for data for cone cell responsivity (color vision)

AI Thread Summary
The discussion centers on obtaining numerical data related to color vision plots, specifically regarding the experiments that generate this data, such as whether cone cells are directly measured or if human color matching is involved. There is an interest in creating a function to map wavelengths to RGB values using the data. Participants also seek recommendations for primary sources in the field of color vision research. The original poster later found a relevant PDF with data and a valuable resource on color vision at cvrl.org, expressing a desire for further information and assistance from the community.

Hello,
1) I am looking for numerical data behind plots like this one.

2) Also, any information on the experiments the data comes from would be helpful. Are cone cells directly measured, or does it involve a human matching colors to a pure color light source?

3) Will I be able to write a function that maps wavelengths to RGB values using said data?

4) What are some good primary sources in this field?

Thank you for answering any of these or just commenting!

EDIT: The link above actually links to a PDF with the data, so never mind that part of the question.
EDIT2: I found this great resource of data on color vision: http://www.cvrl.org/

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
