Webground. We prove the general nondegenerate asymptotic behavior as con-jectured by Basor and Tracy. We also obtain asymptotics of Hankel de-terminants on a nite interval as well as determinants of Toeplitz+Hankel type. Our analysis is based on a study of the related system of orthogonal polynomials on the unit circle using the Riemann-Hilbert ...
