    18 Initial calibration was to take a small section of the data (18:42 to 19:06) to compute the bandpass correction (with mfcal). No time-variable was bandpass applied.
     18Initial calibration was to take a small section of the data (2009-04-11_18:42 to 19:06) to compute the bandpass correction (with mfcal). This bandpass correction was applied to all the data on either side of this time range. No time-variable was bandpass applied.

    20 The first interesting feature (after applying the bandpass correction and taking out the median amplitude and phase of the spectrum at each time step) is that there is a clear systematic change in phase gradient (ie astronomical phase as a function of channel number) with time, that has larger amplitude and varies faster on longer baselines.
