Monopole and dipole components evaluated at locations obtained by rotating the T1 cluster template about the Z axis. The dot-dashed (blue) line shown in the upper right panel marks the amplitude measured at zero rotation. The bottom two panels show the direction of the dipole measured for a given rotation angle. Note the pronounced inhomogeneities in the resulting sampling of all possible random dipoles, as well as the 120° periodicity in the amplitude of the monopole.
