Angle-average void-galaxy correlation function as a function of radial distance normalised to the void radius. To demonstrate the anisotropy we average over two angular wedges, along the line of sight (α< 30°, black line) and transverse to the line of sight (α> 60°, red line). The shaded regions represent the spread of values measured in the mocks. The enhancement along the line-of-sight is an indication of the redshift-space distortion produced by the outflow of galaxies from voids.
