Measuring transverse magnetic fields: the influence of a polarized continuum
Observatoire Midi-Pyrénées, 14 Av. Belin, 31400 Toulouse, France
The diagnosis of stellar magnetic fields must include the determination of the transverse field component, thus the measurement of linear polarization across spectral lines. While the neighbouring continuum is often considered as a zero reference level, it can be polarized by various scattering mechanisms. I discuss some consequences of such a superposition.
