  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)=0.69+/-0.02, (m-M)_V=15.02+/-0.07 and 11+/-2 Gyr for NGC 6366.
