color-magnitude diagrams • use HST ACS/WFC VEGAmag photometric system for data and isochrones • Z=0.2Zs isochrones (Leo Girardi) , E(B-V)=0.11 • (a) t=1e7,5e7,2e8,5e8 years (b) t=1e7,5e7,3e8,1e9,3e9
color-magnitude diagrams • two populations • young: < a few 10 7 years • old: 3-30x10 8 years • ULX age for E(B-V)=0.11 mag • 10 7 years from F435W-F555W • 3x10 7 years from F555W-F814W • two ages converge at 5 X10 6 years for E(B-V)= 0.33 mag [E(B-V)=0.44 mag from X-ray absorption] • initial/current mass of 52/8.5 Ms, radius of 7 Rs
