Near-IR colour–colour diagram based on 2MASS magnitudes. The thick black dots lower-left mark the locus of intrinsic colours for main sequence dwarfs and giants (Koorneef 1983); the two long-dashed parallel lines are reddening vectors for the main sequence stars up to Av = 30 mag (Rieke & Lebofsky 1985); the short-dashed line indicates the locus of T Tauri stars (Meyer et al. 1997).
