The internal reconciliation of the distance scales using the first derivative of the angular velocity of Galactic rotation {\\Omega}'0 and the external reconciliation with Humphreys's distance scale for OB associations refined by Mel'nik and Dambis show that the initial distances should be reduced by \\approx 20%. Given this correction, the heliocentric distances of these stars lie within the range 0.6-2.6 kpc.
