26. p are the usual delta functions accounting for the conservation of momentum and energy. f̃ and f are the single particle phase space distribution functions for thermal bosons and for fermions, respectively.
27. Here, the term "hydrodynamic" refers only to the dynamics of the Fermi gas. For the condensate, it is always in the hydrodynamic regime as described by the Stringari hydrodynamic equation.

36. -2/5. Both of them are valid for parabolic confinement for a pure condensate. From Fig. 1(a), the former relation gives Δω/ω=25% and the latter gives Δω/ω=17%. The possible reason for the discrepancy might be the fact that the density profile of the condensate in the mixture is not perfectly parabolic. Nevertheless, a rough estimate of Δω/ω≈20% is convincing.
37. If the critical temperature for superfluidity is high enough, both the normal and the superfluid phases may be governed by the same hydrodynamic regime over the whole range of relevant temperatures.

39. 0. Therefore, the inclusion of the possible effect of gravitational sag may not be able to fully resolve the discrepancy mentioned in the paper.
