  We present femtoscopic results from hydrodynamics-inspired thermal models
with single freeze-out. Non-identical particle femtoscopy is studied and
compared to results of identical particle correlations. Special emphasis is put
on shifts between average space-time emission points of non-identical particles
of different masses. They are found to be sensitive to both the spatial shift
coming from radial flow, as well as average emission time difference coming
from the resonance decays. The Therminator Monte-Carlo program was chosen for
this study because it realistically models both of these effects. In order to
analyze the results we present and test the methodology of non-identical
particle correlations.
