A summary of polarimetric results for the large r =4.5′ region encompassing Sgr A complex (excluding r =1′ regions around G0.13-0.11 and the brightest reflection spot) in the 3 – 6 keV energy band.

Notes. The results are split for the first and second observations separately, their combination, and the combined results for each IXPE Detector Unit (DU). The normalized Stokes q=Q/I and u = Q/I parameters, and the corresponding PD, are determined with respect to the total intensity in the 3–6 keV band. It is different from the PD of the reflected continuum only and is intended to demonstrate consistency and variations between individual datasets. Whenever the detection’s statistical significance level Σ is below the 3σ threshold (unaffected by the choice of relative normalization), the 1σ upper limit on the PD is provided, whereas the PA is non-constrained (NC).
