Fig. 4
Scan-preaveraged parallel-hand (RR) autocorrelation spectra in the upper spectral roll-off region of the baseband for a subset of continuum calibrator scans at antenna LA spanning the range of geometric fringe-rate over the course of the observing run. Fringe rates are given in units of channel width, and frequency channels 1–128 span the baseband bandwidth of 4 MHz.
