Examining the variation

Make sure the output column is set to DATA, open up the TDL options and click 'simulate MS' to write the visibilities.

As with the gain variation (which we also apply as usual) the bandpass variations are different per-antenna.

Remember you can use the Meqbrowser to view any arbitrary node in the tree. In the screen grab below we are viewing the bandpass shapes for antennas 0, 6, 9 and 13.

The horizontal axis is frequency (and so consists of 64 bins), the vertical axis is time and the colour scale is gain, which as you can see from the bar runs from 0 to 1. These plots show the varying slope of the bandpass with time. The different plots for different antennas should also convince you that the effects are different for each of them.
