Azimthally sensitive femtoscopy and v2
  I investigate the correlation between spatial and flow anisotropy in determining the elliptic flow and azimuthal dependence of the HBT correlation radii in non-central nuclear collisions. It is shown that the correlation radii are in most cases dominantly sensitive to the anisotropy in space. In case of v2, the correlation depends strongly on particle species. A procedure for disentangling the spatial and the flow anisotropy is proposed.
