Notes.

^(a)

Positions are derived as the centroid of surface brightness maps from 2MASS K_s band images.

^(b)

⟨ A_{K_s field} ⟩ is the average A_{K_s} of the spectroscopically observed late-type stars in the field.

^(c)

DM(⟨ A_{K_s field} ⟩) is the distance modulus obtained from the A_{K_s} values of detected late-type stars and the model of Drimmel et al. (2003).

^(d)

⟨ A_{K_s RSGs} ⟩ is the average A_{K_s} of the detected RSGs.

^(e)

DM(⟨ A_{K_s RSGs} ⟩) is the distance modulus obtained from the A_{K_s} values of cRSGs and the model of Drimmel et al. (2003).

^(f)

DM(red clump) is the distance modulus obtained from the A_{K_s} values of cRSGs and field red clump stars.

^(g)

DM(Sp): spectro-photometric distance modulus of star 39, by assuming a giant case (O9.5-B3III). For a dwarf case, DM would be 13.02 ± 0.77 mag.
