The moral of today: One measurement is not a measurement. Practically the only two things I can do is to build the stimulator circuit and get an other photometer to make sure it’s not a calibration artifact. Then, all I can do is wash my hands how Pontius Pilate did. Then, I have locked out all possibility to have a misconducted measurement, and then, I can say is that my measurement is indeed correct no matter how wacky and unrealistic it seems. So the question is now if I have something publishable or more modest. Two weeks to go.
