Figure caption: Dispersion analysis of the POL-2 and Planck polarization segments toward the DR21 filament. For each source, the analysis of the angular dispersion function is plotted in the top panel, and the correlated component of the dispersion function is plotted in the bottom panel. Top panels: the dots represent the mean values of the data, and the error bars show the standard deviations of the mean values. The blue line shows the best fit to the data (Equation (4)), and the red line shows the ordered component ﹩{a}_{2}^{{\prime} }{l}^{2}+{b}^{2}(0)﹩ of the best fit. The dotted vertical and horizontal lines denote the beam size and the expected value for random magnetic fields, respectively. Bottom panels: the dots represent the correlated component of the best fit to the data. The blue line shows the turbulent component b 2(l) of the best fit, and the red line shows the correlation due to the beam (i.e., b 2(l) when δ = 0).
