Abstract
Context. In the notes to Table 1, a unit conversion was incorrect. The text should read 1  Gyr ^-1=6.02e+13 g s^-1. As a consequence in the 3rd paragraph of Sect. 3, the mass loss taking place in  Boo b should be  Gyr^-1 for  g cm^-3, or  Gyr^-1 in Earth mass units. Independently, the values of `` accumulated'', in Col. 12 of Table 1 were calculated using an obsolete formula and were thus slightly underestimated, generally by 0.2. As a consequence Fig. 2 should show all values at a slightly higher position, although this is of no relevance for the conclusions of the paper. Table 1 and Fig. 2 are reproduced in their correct version here. At the end of 5th paragraph of Sect. 2, the hard limit of X-ray flux accumulated after 10 Gyr should be  10^22.14 erg cm^-2, instead of  10^21.76 erg cm^-2, and our highest flux is now  10^21.23 erg cm^-2 instead of  10^21.05 erg cm^-2.
