    • ij(i≠j = 0,1,2) are held fixed. For a compressible system, we need the additional requirement that βP should be kept fixed and finite. It should be stressed that the RMA limit of all thermodynamically consistent theories is the same and, hence, unique; furthermore, this limiting theory reduces to the F-H theory in the incompressible limit.

    • The thermodynamic quantity Γ must be related to the intensity of scattering. Since the scattering intensity depends on extraneous parameters like the scattering lengths, we must also ensure that Γ is independent of all extraneous parameters.

    • 02, respectively. However, we have found that these effective chis are not reliable estimators. Here, S ̃ ij (C) is the matrix element of the inverse matrix S ̃ (C) ≡ (S (C)) - 1, S (C) being the 2 × 2 matrix formed by S ij (C).

    • The experimental choice of Γ that is used in Eq. (3) need not coincide with our definition in Eq. (12).
