Can you help me understand the class of problems solvable by a nondetermimistic Turing machine with an oracle for SAT running in polynomial time?

Obviously it contains Sigma2 union Pi2, but what else?

Characterize How can one characterize NP^SAT?

Can you help me understand the class of problems solvable by a nondetermimistic Turing machin machine with an oracle for SAT running in poly polynomial time?

Obviously it contains Sigma2 union Pi2, but what else?

Btw someone should create a Complexity tag; I can't do it since I'm a new user.
