This is an erratum to the paper entitled “The galaxy population of the complex cluster system Abell 3921” published in A&A. An error was made in computing SFRs following Kennicutt (1992). We used R-band instead of B-band luminosities, which led to an underestimation of SFRs by a factor of ~23. Formula (1) in the original paper should read (1)Since we do not have B-band imaging for the galaxies in the area of Abell 3921, the B-band luminosities used for the corrected SFR values shown in Fig. 1 and Table 1 were calculated after transforming apparent R-band to apparent B-band magnitudes. For this transformation we used synthetic photometry based on the SED classification described in the original paper. We tested this approach with a sample of galaxies at similar redshifts, for which both B- and R-band imaging is available, and find that systematic errors are negligible (<0.1 M/yr).

All results and conclusions in the original paper remain unchanged.
