Hello!
Sorry for off-topic question, but I believe someone will be able to
answer.
At the university I have the opportunity to use Photo Research PR-650
Spectroradiometer
http://www.photoresearch.com/current/pr650.asp
The data that I get from this instrument are spectral power
distribution from 380 to 780 nm with 4nm interval and in W/m^2*nm.
The question is are those spectral data directly usable to calculate
CIE tristimulus values or should I somehow normalize
those spectral values.
Thank you in advance, Best regards Andrej Javorsek
