  Combining three numerical methods (forward flux sampling, seeding of
droplets, and finite size droplets), we probe the crystallization of hard
spheres over the full range from close to coexistence to the spinodal regime.
We show that all three methods allow to sample different regimes and agree
perfectly in the ranges where they overlap. By combining the nucleation work
calculated from forward flux sampling of small droplets and the nucleation
theorem, we show how to compute the nucleation work spanning three orders of
magnitude. Using a variation of the nucleation theorem, we show how to extract
the pressure difference between the solid droplet and ambient liquid. Moreover,
combining the nucleation work with the pressure difference allows us to
calculate the interfacial tension of small droplets. Our results demonstrate
that employing bulk quantities yields inaccurate results for the nucleation
rate.
