[M/H]-[α/Fe] distributions of stars in different distance intervals, 5.5−6.5, 7.5−8.5 and 9.5−10.5 kpc from the Galactic center. These plots illustrate that the region where the probability of finding a solar metallicity and solar alpha-abundance star is highest beyond the solar orbit, at R = 8.89 kpc. Arguing from chemical offsets that the Sun comes from the inner disk is not supported by the APOGEE survey.
