  Analyzing the m_t-spectrum and two-particle correlations of negative hadrons
from 158 AGeV/c Pb+Pb collisions at slightly forward rapidities we find a
(thermal) freeze-out temperature of about 100 MeV and transverse flow with
<v_t> approximately 0.55c. The M_t-dependence of the correlation radii prefers
a box-like transverse density profile over a Gaussian. From an analysis of the
pion phase-space density we find pion chemical potential of approximately 60
MeV at thermal freeze-out.
