-    "For MSPs, polarization arises from Thomson scattering or comptonization by an accretion shock formed above the hot region. In the case of Thomson scattering, the degree of polarization depends on the angle of propagation respect to the local surface normal. The polarization angle for the emission site is governed by the rotating vector model, which incorporates the oblate shape of the NS and relativistic effects due to the rapid rotation. This simple case is one the implemented in this tutorial. For the case of comptonized atmosphere, details can be found in [Bobrikova et al. (2023)](https://ui.adsabs.harvard.edu/abs/2023A%26A...678A..99B/abstract)\n",
