Recently, we discovered a bug in our population synthesis (PS) code presented in A&A 2008, 482, 617. This bug concerns the application of the improved ISM models to calculate the absorbed X-ray flux. The code erroneously did not cover the whole Galactic coordinate (l, b) range of the ISM-models to obtain the absorbing column density N(H). Instead, only a small region (Delta l approximate to 7 deg, Delta b approximate to 7 deg) around the Galactic Center was used, which led to a significant overestimation of the absorption translating into an underestimation of the predicted neutron star number.
While all our main conclusions remain valid we report in the following on some details regarding the corrected results.
