Because of an unfortunate mistake, a rough reddening correction from earlier works was left in the average V magnitudes of the variables of M 4. Therefore, the reddened distance modulus ( $\langle\tilde d_V\rangle$) for this cluster is incorrectly given in Table 9. The correct value of $\langle\tilde d_V\rangle$ is -4.43 instead of -5.69 as given in the paper. The above mistake does not affect any other parts of the paper, including the dereddened distance moduli of M 4.
