We present panchromatic isochrone fits to the color magnitude data of the globular cluster NGC 6366 , based on HST ACS/WFC and SOAR photometric data .
Before performing the isochrone fits , we corrected the photometric data for differential reddening and calculated the mean ridge line of the color magnitude diagrams .
We compared the isochrones of Dartmouth Stellar Evolution Database and PAdova and TRieste Stellar Evolution Code ( with microscopic diffusion starting on the main sequence ) .
Based on previous determinations of the metallicity of this cluster we test it from [ Fe/H ] =-1.00 to [ Fe/H ] = -0.50 , and the age from 9 to 13 Gyrs .
The uncertainties do not decrease when we fit simultaneous colors .
We also find that the Dartmouth Stellar Evolution Database isochrones have a better fit in the sub giant branch and low main sequence than the PAdova and TRieste Stellar Evolution Code .
Considering the most recent spectroscopic determination of the metallicity ( [ Fe/H ] = -0.67 ) , we find E ( B-V ) =0.67 \pm 0.02 , ( m-M ) _ { V } =14.94 \pm 0.05 and 11 \pm 2 Gyr for NGC 6366 .
