Enumeration
NumCosmoHIPertITwoFluidsObs
Description [src]
Enumeration of physical observables computed from the two-fluid perturbation state.
Notes: - The quantity $k_\mathrm{phys}\mathcal{V}\mathrm{diff} = k\mathrm{phys}(\mathcal{V}r - \mathcal{V}_w)$ reflects differences in velocity potential. - The isocurvature perturbation is $\delta{\text{diff}} = \delta_r - \delta_w$. - The total curvature perturbation $k_\mathrm{phys}\mathcal{V}{\text{tot}}$ is computed as a weighted average of the components. - The total density contrast $\delta{\text{tot}}$ may be computed as a weighted average of the components.
These observables cover adiabatic, isocurvature, and component-specific quantities, and are suitable for correlation and power spectrum evaluations.
