Pulses displayed on this page: 1 - 300

Fig. 1. Intensities of all single pulses. Vertical lines indicate which segments are displayed in Fig. 2 below. Black horizontal line shows the intensity of the average profile of the whole data set.

Fig. 2. Lower panels show segments of 300 consecutive single pulses (100 pulses in each graph). Each single pulse is normalized, then 11 levels of intensity is shown with symbols of different sizes. Horizontal axis is in sample numbers, vertical axis shows pulse numbers, increasing from the bottom. Red vertical graph on the right-hand side of each graph shows maximum intensity of each single pulse. Each vertical graph is also normalized in order to show changes in the intensities of single pulses.
Upper panels show the average profile of the whole data set (black line), and the average profile of the segment of 100 pulses displayed in the lower panel (red line).
