We have studied the behavior of 36 different time distributions with core distance for ten different bins of secθ using only SD data. We have parametrized this behavior with a quadratic function, fixing the value at the origin. An optimal range of core distance were the parametrization is valid was found for each time distribution. The obtained parameters as a function of secθ where analyzed. Special cases are discussed, and a comparison with the well known risetime parametrization it is also shown.
