ΔF/F derived from the velocity offsets in Table 1 versus the redshift (left), distance from the dipole (middle) and the product of the look-back time with the cosine of the distance from the dipole (right), cf. Webb et al. (2011). The filled black markers show the eight [C i] sources and the unfilled colour markers the two [C ii] sources (see Levshakov et al. 2008).
