Caption: Figure 1.

Geometry of a hot spot on the surface of a neutron star rotating at an angular frequency Ω. A photon emitted from the surface at an angle α with respect to the local surface normal ﹩{\boldsymbol{n}}﹩, as seen in the local static frame, deflects by a total angle ψ as it travels to a distant observer. Figure adapted from Bogdanov (2016).
