The Impact of Point-Source Subtraction Residuals on 21 cm Epoch of Reionization Estimation

Precise subtraction of foreground sources is crucial for detecting and estimating 21 cm H I signals from the Epoch of Reionization (EoR). We quantify how imperfect point-source subtraction due to limitations of the measurement data set yields structured residual signal in the data set. We use the Cr...
