Frequency evolution of burst widths from GMRT (green circles), Effelsberg (blue circles), and CHIME (red crosses). Distributions at each frequency are shown as violin plots in logarithmic space, with mean values and corresponding uncertainties indicated by black points with error bars. The dashed black line represents the weighted power-law fit across all frequencies (GMRT+Effelsberg), while the solid black line shows the fit using only Effelsberg data. Both fits are performed in log–log space, yielding power-law indices, α, as indicated in the legend.
