By means of the comparison between the observedcluster sequences and the Padova theoretical isochrones, we derive the followingparameters: for NGC 2658, E(B _V ) = E(B _V ) = 0:35+0;05/-0;10, log (age) = 88:50+0;25/-0;05 , and(m _ M)0 = 13:32+0;36/-0;52; for NGC 2849, the reddening is in the range 0.46 to 0.57with an uncertainty of _0:12 mag, (m_M)0 = 14:02+0;38/-0;40, and log (age) = 8:8+0;1/-0;05;finally, for NGC 3247 we obtain E(B_V ) = 0:39 _ 0:07, log (age) = 7:60+0:4/-0:3, and(m _ M)0 = 11:89+0:51/-0:45. In this study the isochrones have been renormalized tothe solar values (B_V )_ = 0:65 and MV = 4:84; the values (V_R)_ = 0:37 and(V_I)_ = 0:70 are proposed as zero points in order to renormalize those colors aswell. 2003 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57139104 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.39 |
