Evolution of the position of the hot spot during accretion (ν
s
= 4.1 ms). μ
represents the magnetic dipole axis. Note how the densest portion of the
circular hot spot (encoded by the ρ
scale, bottom right) shifts during time even if the observer is in the rotating reference frame of the NS (Figure from [11])
