FUV−F435W vs. F435W−F814W diagram for NGC 2623 clusters. The color coding is the same as in Figure A.1, but only those clusters with S/N> 5 in FUV, F435W, and F814W filters are included in the plots. The black solid line is the path described by SSPs from 1 Myr to 13 Gyr, Z_⊙, and A_V = 0 mag. The gray-scale lines are the paths for the same models reddened by 1 to 3 mag, with the lighter shades tracing the more extincted models.
