Fig. 4: The Figure of Merit (FoM) of each individual parameter derived from all power spectrum combined, rescaled by those derived from \({P}_{{{{{{{{\rm{pre}}}}}}}}}+{B}_{0}\).
From: Extracting high-order cosmological information in galaxy surveys with power spectra
The quantities X in (a) and Y in (b) are defined as the FoM of each individual parameter with or without all other parameters fixed. Specifically, \(X\equiv \sqrt{{F}_{ii}}\) and \(Y\equiv 1/\sqrt{{C}_{ii}}\) where F is the Fisher matrix and C ≡ F−1. D0 and D1 denote Pall and \({P}_{{{{{{{{\rm{pre}}}}}}}}}+{B}_{0}\) respectively. The dark and light grey bars in each panel show the cases with k = 0.2 and 0.5 hMpc−1, respectively. The vertical dashed lines show a full recovery of information from dataset \({P}_{{{{{{{{\rm{pre}}}}}}}}}+{B}_{0}\). The smoothing scale is set to be 10 h−1Mpc when performing the reconstruction.
