Examples of the synthetic azimuthal pattern. Azimuthal variations of delays calculated by synthetic dataset are shown as examples. We showed three examples with 10, 5, and 0 ms of \(\updelta {\mathrm{t}}_{0}\) in Eq. (8). We provide \(\mathrm{A}=1,\updelta {\mathrm{t}}_{1}=1 \left[\mathrm{ms}\right],\updelta {\mathrm{t}}_{2}=2 \left[\mathrm{ms}\right]\) in Eqs. (8) and (9) for this calculation
