(Appendix B, Figures) Polarization flare of 3C 454.3 in millimeter wavelengths seen from decadal polarimetric observations

Year: 2025

Type: article

Abstract: The B.1. Figures describe the observational results from the KVN single-dish showing flux density (first column), spectral index (α, second column), polarizationdegree (m_p, third column), observed polarization angle (χ_obs, fourth column), and estimated RM in logarithmic scale (fifth column). The filledand open dots in the first and second columns indicate total and linearly polarized emission, respectively. The indicated RM_fit values in the fourthcolumn are in order of 10^3 rad m^−2. The grey shaded area in the last column indicates the range of |RM_fit|. The red solid lines in the fourth and lastcolumns are the fit models to χ = χ_0 + RM λ^2 and |RM| ∝ ν_a, respectively. The corresponding observing dates are noted in the first column. Theminor ticks in the fourth column indicate 5 degree variation The B.2. Figure shows absolute RM values from the KVN observations containing at least two frequency pairs. The grey shaded area is the same as inFigure B.1.
