The black curve represents the locus of typical red giant stars at different distances along a line of sight with an extinction of cK = 0.15 kpc-1 and E(J − Ks) = 1.5 ± 0.2 AKs as determined by Indebetouw et al. (2005) for the diffuse ISM. The dashed curves represent the error estimates by these authors. The red curve (on top of the full drawn black curve) represents our determination of star #2 with cK = 0.105 kpc-1 and E(J − Ks) = 1.96 AKs.
