the schwartz atlas is built from 3T data, which has somewhat different contrast properties due to the field-strength dependence of T1
Hopefully somone else can answer b) as I don't remember.

I would like to know the following: a) what is the differences between the 3T Atlas (schwartz atlas) and the standard atlas? b) what does the 3T-specific NU intensity correction parameters do differently than the standard?

However, where can i find the documentation for the above?
Best regards, Kasper
