The paper ``Suppressed radio emission in supercluster galaxies: enhanced ram pressure in merging clusters'' was published in A&A 475, 169. There is a double typographical error in Appendix A. In Eqs. (A.2) and (A.9), which both express the squared aperture velocity dispersion of a respectively general and NFW (Navarro et al. 1996) spherical system, there is
a factor 3 missing in the terms in front of the integrals, so that the squared aperture velocity dispersion should be 3 times smaller than given.
These two equations should thus read
However, all other equations (in particular Eqs. (A.10) and (A.11)) are correct as is the accompanying discussion.

- This factor of 3 is also missing in Eq. (B.7) of Mamon & okas (2005), as reported by Mamon & okas (2006).
