Absolute K-band magnitudes for non-stellar sources in NGC 2997 with errors  < 03 as functions of Q_d and (J − K) indices. Padova and SB99 SSP models for a cluster with 10⁵ M_⊙ are given by blue full-drawn and red dashed lines, respectively. The color coding indicates the other index, where red corresponds to 15  <  (J − K) and 01  <  Q_d, respectively. The “dusty” reddening line is shown for A_V = 5^m.
