Statistical significance of the three dipole components and the dipole amplitude measured using the I_E data and assuming the CMB dipole template, Eq. (6). Black, green, red full circles correspond to the X, Y, and Z dipole components; blue open circles to the overall dipole amplitude d. The left panel (a) shows the result after one year of integration and the right panel (b) at the end of the 6-year mission. The fraction of the total number of galaxies in samples a and b are, from left to right, f_a = [0.5, 0.2, 0.1, 0.2, 0.2, 0.2, 0.15, 0.1, 0.2] and f_b = [0.5, 0.3, 0.3, 0.25, 0.2, 0.2, 0.2, 0.2, 0.1], respectively. For other configurations the S/N will increase according to Eq. (32).
