Luckily there is some 1934-638 data, so we calibrate our bandpass with that: 28 28 29 29 `mfcal vis=cx167.uv "select=source(1934-638)" interval=0.1` 30 30 31 31 Giving the same `uvspec` command as before we now get: 32 33 [[Image(cx167_example_plot2.png)]] 34 35 There is some obvious narrowband interference present in the data.
