That sounds fine so I'm happy for you to use it. Is this email sufficient authorisation or would you like something else?
I suggest you review my validation software carefully to ensure that you are happy with the way in which I have validated the software. Or you might like to develop your own validation tests for it. Please ask me if you have any questions about anything.
Cheers,
Mike

Nobody is allowed to extract it and use it independently of OpenTURNS without your written permission, but of course anybody using OpenTURNS in a commercial product can use your code through its openTURNS interface (ie the Poisson::computeQuantile() method)

OpenTURNS is made of contributions from many horizons, including several academic teams in Europe. I am sure that your work will be both appreciated and valorized by our users, mainly Electricité de France, Airbus (including Airbus UK at Filton) and many others.
