Left panel: The contour plots between Π_X and Ψ_X measured in the 2–8 keV band using the PCUBE (red) and XSPEC (blue) analyses. The red and blue crosses are the best-fitted values of Π_X and Ψ_X. The contours are plotted in 68% (χ² = 2.28), 90% (χ² = 4.605) and 99% (χ² = 9.21) confidence levels. Right panel: The polarization degree Π_X and polarization angle Ψ_X contour plots as obtained from the 5.66–8 keV PCUBE (black) and XSPEC (orange) analyses. The black and orange crosses are the best-fitted values of Π_X and Ψ_X. The contours are plotted in 68% (χ² = 2.28), 90% (χ² = 4.605) and 99% (χ² = 9.21) confidence. The black dashed line represents the radio jet position angle (∼8.5°) of NGC 2110. The black shaded region is the error in jet position angle. The blue shaded regions denote the MDP₉₉ value at the 99% confidence.
