Color–color diagram for non-stellar sources in NGC 2997 with errors  <005. Evolutionary tracks for a stellar population are shown where the full drawn line is for a Padova SSP model while the dashed line indicates a SB99 CSP model. The color coding of the points indicates their absolute magnitude M_K. A standard “screen” reddening vector and one for a “dusty” cluster medium are shown for A_V = 5^m.
