Patterns of primary beam non-redundancy in close-packed 21 cm array observations
(Oxford University Press, 2021)
Radio interferometer arrays such as HERA consist of many close-packed dishes arranged in a regular pattern, giving rise to a
large number of ‘redundant’ baselines with the same length and orientation. Since identical ...
Characterization of inpaint residuals in interferometric measurements of the epoch of reionization
(Monthly Notices of the Royal Astronomical Society, 2023)
To mitigate the effects of Radio Frequency Interference (RFI) on the data analysis pipelines of 21 cm interferometric instruments, numerous inpaint techniques have been developed. In this paper, we examine the qualitative ...
