Statistical analysis of the causes of excess variance in the 21 cm signal power spectra obtained with the Low-Frequency Array

Fig. 13

Spherically averaged power spectrum estimated from one-night (L246309) Cas A and Cyg A only simulation. Compared the Cas A and Cyg A introduced Stokes I power to the estimated 21 cm signal at k = 0.1 hc Mpc^–1, the Cas A and Cyg A power should be reduced by ~99.3% or even higher in the calibration to be able to distinguish the 21 cm signal from the Cas A and Cyg A power.
