Radio Frequency Interference (RFI) is one of the systematic challenges preventing 21cm interferometric instruments from detecting the Epoch of Reionization (EoR). To mitigate the effects of RFI on data analysis pipelines, numerous inpaint techniques have been developed to crudely restore RFI corrupted data. In this paper we examine the qualitative and quantitative errors introduced into the visibilities and power spectrum due to inpainting. We perform our analysis on simulated data as well as…
