Cylindrical power spectra at different stages of calibration and source subtraction. Top row: cylindrical power spectra after preprocessing (“Data”), after A-team subtraction (“Ateam Sub”), after DI correction (“DI Corr”), after 3C subtraction (“3C Sub”), after NCP Subtraction (“NCP Sub”), and after post-calibration RFI flagging (“Postflag”). Bottom row: ratio of successive power spectra in the top row. This shows how much power has been subtracted and from which part of the k space at the different calibration stages. The rightmost plot in the bottom row is the ratio of the power spectrum of the data after post-calibration RFI flagging to the noise power spectrum obtained from time-differenced Stokes-V data. Note that the color bars for all plots in the same row are the same, except for the plot on the extreme right in the bottom row.
