Extracted Washington T₁ versus C − T₁ CMDs for stars distributed within the cluster radii (small circles), and the cluster cleaned from field contamination (big circles): 1) BSDL 716, 2) BSDL 1024, 3) BSDL 1035, 4) BSDL 2995, 5) H88-26, 6) H88-40, 7) H88-55, 8) H88-188, 9) H88-245, 10) H88-333, 11) HS 38, 12) HS 151, 13) HS 154, 14) KMHK 229, 15) KMHK 506, 16) KMHK 1045, 17) KMHK 1055, 18) LW 469, 19) NGC 2093, 20) SL 154, 21) SL 229, 22) SL 293, 23) SL 300, 24) SL 351, 25) SL 510, and 26) SL 588. The three available isochrones of Girardi et al. (2002) which best resemble the cluster features are overplotted.
