Panel a): Polarised intensity at 5430 MHz with contours starting at 3σ_PI and increasing by $\sqrt{2}$ (σ_PI = 8.39 μJy beam⁻¹ RMSF⁻¹). Panel b): Fractional polarisation at 5430 MHz with PI contours as in panel a). Panel c): Polarised intensity with total intensity contours at 5430 MHz starting at 3σ and increase by a factor of two (σ = 11 μJy/beam). The magnetic field orientations are shown in black and scale with the polarised intensity. Panel d): Foreground-corrected rotation measure with total intensity contours as in panel c). For each panel, the circular beam of 6″ appears in the lower left corner.
