Characterizing burst shapes in dense cultures. A Parameters that define the shape of population bursts. We measured the ASDR as a function of time during the burst, smoothed with a 10 ms Gaussian filter. The 20% and 80% points between baseline and peak ASDR were determined and used to define the various phases. B Total duration of individual bursts. (Note log scale on y-axis.) C Duration of onset phases. D Duration of offset phases. In all panels, dots represent individual bursts, horizontally jittered for clarity, and colored by plating batch. Lines are interpolated averages, computed in log-space, using a Gaussian window with a half-width of 1 day.
