This is the second of two papers presenting a detailed examination of Fokker-Planck models for the globular cluster NGC 6397 and is concerned with extracting information on the cluster from the models .
The models give a current cluster mass of 6.6 \pm 0.5 \times 10 ^ { 4 } M _ { \mathord { \odot } } of which about 2500 M _ { \mathord { \odot } } is in neutron stars .
This mass gives a V -band mass-to-light ratio of 1.2 in solar units .
The models and data provide weaker estimates of the structural parameters , but suggest that the core radius is less than 0.3 pc ( 11″ ) and the tidal radius is 17 \pm 4 pc .
In turn , by assuming a flat rotation curve for the galaxy , the mass and tidal radius suggest that the latter was set at a distance of 2.5 kpc from the galactic center .
