ABSTRACT We study the viability of using power spectrum clustering wedges as summary statistics of 21 cm surveys during the epoch of reionization (EoR). For observations in a wide redshift range $z\sim 7{\!-\!}9$ corresponding to a line-of-sight scale of $\sim 500\,$ Mpc, the power spectrum is subje...
