Figure 5$a$ shows the genus for the northern and southern hemispheres measured from the W band data. Both genus curves have different genus amplitudes, especially at the negative threshold levels. We measure amplitude differences, $A_{-}^{\rm N} - A_{-}^{\rm S}$ and $A_{+}^{\rm N} - A_{+}^{\rm S}$, from the observed W band map (Kp0-masked) and its 500 mock maps, and list the result in Table 3. Here $A_{-}^{\rm N(S)}$ is the amplitude obtained by fitting the genus points at $\nu_A < 0$ measured in the northern (southern) hemisphere with a fitting function
