The paper ‘Effect of magnetic activity saturation in chromospheric flux–flux relationships’ was published in Mon. Not. R. Astron. Soc. 414, 2629–2641 (2011). In the published paper there were misprints affecting the numbers in columns 3 and 4 of Table 2, and in columns 4 and 5 of Table 3. The correct values are presented in the following tables, which replace those in the published paper. We note that these changes have no effect on the figures in the paper.

Table 2.  Linear fit coefficients for each flux–flux relationship found in this paper and in previous studies.
