Equation (1) of our original paper was incorrect and should have readv2inner-v2f~2MG/(Rinner). (1)For the values of the outflow velocities vinner and radius Rinner that we adopted at the inner edge of the outflows, and vf, the final velocities we cited for large radial distances from the stars, this requires revision of the calculated stellar masses. The corrected masses for NML Cyg and VY CMa become MNML~53Msolar and MVY~27Msolar, respectively. If we assume parabolic outflow, instead of FWHM velocities, the terminal velocities vf can be taken to be 26 and 20 km s-1, respectively, instead of 19 and 17 km s-1, and the corresponding stellar masses become MNML~41Msolar and MVY~22Msolar.
Neither the calculated mass-loss rates that we cite in our paper, MNML>~2.4×10-4Msolar yr-1 and MVY>~3.3×10-4Msolar yr-1, nor any other aspects or conclusions of the paper are affected by this correction.
