Noise standard deviation, in SEFD units, estimated from the channel-differenced noise at each uv-cell, after sky-model subtraction. Data are shown for the Stokes-I 10 nights combined z≈9.1 data cube. The trace of the Cas A and Cygnus A sources in the uv plane, which are fully flagged, are denoted with a blue and orange line, respectively.
