Particle Dark Matter Constraints: the Effect of Galactic Uncertainties": values of the stellar mass of the Milky Way (MW) in column 4 of table 1, values of the total MW mass quoted in text, and a typo when referring to the value of the total MW as quoted in the Sagittarius stream paper [1].Here we provide a correct version of table 1 (stellar mass of the MW corrected, column 4), and replace the final, corrected version of the text (original lines below table 1 in page 5).No other element of the paper has changed, and conclusions are unaffected.
