Corrections to Table 2.2B of Volume IV of International Tables for X-ray Crystallography

Corrections are given for two of the coefficients for the analytical approximations to X-ray scattering factors in Table 2.2B of International Tables for X-ray Crystallography [(1974), Vol. IV. Birmingham: Kynoch press]. For Ru⁺⁴ (p. 100), the coefficient b₃ should be 0.036495 rather than 0.36495; for Bi⁺⁵ (p. 101), the coefficient b₂ should be 0.039042 rather than 0.39042.
