Observed power spectrum and frequency-angular power spectrum
The two-point summary statistics is one of the most commonly used tools in the study of cosmological structure. Starting from the theoretical power spectrum defined in the 3D volume and obtained via the process of ensemble averaging, we establish the construction of the “observed 3D power spectrum,”...
