Query: Bose-Einstein condensation in heavy ion collisions: importance of and
  uncertainties in the finite volume corrections   The density of the Bose-Einstein condensate for non-interacting pions in a
cubic box, at given temperature and (average) total pion density, is
calculaated for three sets of boundary conditions. The densities are much
larger than predicted from thermodynamics and depend significantly on the
choice of the boundary conditions, even for volumes as large as $6.4\cdot
10$fm$^3$.
