(H − K) – (J − H) diagrams for non-stellar sources with errors < 005. The blue full-drawn line show an evolutionary track of a Padova SSP model, while the red dashed line indicates a corresponding SB99 CSP model (for details see Fig. 5). The two black lines show the directions of the reddening vectors for “screen” and “dusty” models (see Fig. 5). Colors indicate the MK of the clusters.
