Multiplicity of crystal planes belonging to the point group -4m2. Erratum

There is an error in Table 10.2.2 of International Tables for Crystallography, Vol. A (Hahn, 1992, 1995). The multiplicity of (00l) and (00) belonging to the point group m2 is 2 not 1. The equivalent reflections in the point group m2 (Ibers, 1967; Ibers & Hamilton, 1973) are hkl = kl = hl = l = kh = h = kl = l. Substitution of h =k = 0 into the above relation results in 00l = 00. Therefore, the multiplicity of 00l or 00 in the point group m2 is 2.
