Visual analysis of the number of emission modes present in the data. Top: 1D histogram of the median location of the peaked profile components shown in logarithmic scale. Middle and bottom: Two profile features plotted against each other in 2D (logarithmic scale) and 1D histograms (linear scale) on the sides. We show contours at 1, 10, 50, 75, and 90% of the maximum bin count. The histograms indicate the presence of at least three stable emission modes in the pulsar and independently confirm our conclusions from the Markov model analysis.
