Radial Flow
The Temperature and velocity
of a common source can be
extracted by fitting midrapidity
Temperature and velocity are
highly correlated, a fit to
a single particle spectrum doesn’t
normally yield a unique result
Consistency check: The input parameters of a simulated source
are recovered from the overlap of the S-R fits to the particle spectra
Assumption: We don’t live in the “dashed” world
