Left, top: Total intensity (solid line) and linearly polarised intensity (solid red circles) from the 28SiO (J = 4 − 3, v = 1) transition. The linear polarisation spectrum is multiplied by a factor of 10. Left, bottom: The linear polarisation fraction (red dots) and electric vector position angle (EVPA) (blue triangles). The horizontal dashed line indicates the EVPA observed in the dust continuum. Right, top: The circularly polarised emission (red short-dashed, multiplied by 100) for the 28SiO (J = 4 − 3, v = 1) transition. Overplotted is also the total intensity derivative dI/ dν (blue long-dashed) scaled for a magnetic field strength of ~2.4 G. Right, bottom: The circular polarisation fraction Pc, which is found to peak at ~0.8% for this transition.
