Observations of G327.6+14.6 (SN1006) compared to a selection of grid-based models. The magnetic field is defined by the components B_x (line-of-sight component), B_y (horizontal component), and B_z (vertical component), where the ratio between the B_y and B_z-components determines the orientation of the bilateral symmetry axis. Top row: observations of SN1006. Left: Stokes I total intensity (MOST). Center: polarized intensity (Reynoso et al. 2013). Right: magnetic field vectors shown with total intensity contours in the background (adapted from Reynoso et al. 2013). Second row: quasi-parallel model with B_x = 0.03μG, B_y = 1.0μG, and B_z = 0.12μG. Third row: quasi-parallel model with B_x = 0.55μG, B_y = 1.0μG, and B_z = 0.12μG. Fourth row: quasi-perpendicular model with B_x = 1.28μG, B_y = −0.12μG, and B_z = 1.0μG. This is very close to the case at the location of SN1006 in the JF12 GMF model. Fifth row: quasi-perpendicular model with B_x = −3.84μG, B_y = −0.12μG, and B_z = 1.0μG. Bottom row: quasi-perpendicular model with B_x = −12.5μG, B_y = −0.12μG, and B_z = 1.0μG. The models are arranged as the data, with far left: Stokes I total intensity; center: polarized intensity, and right: magnetic field vectors shown over total intensity emission.
