Given an integer n ≥ 1 and a truncated Barsotti-Tate group of level n and dimension d over an unequal characteristic valuation ring, we give an explicit bound on its Hasse invariant so that its Harder-Narasimhan filtration has a break which is free of rank d. When n = 1 we also give a local proof of the Abbes-Mokrane ([1]) and Tian ([37]) theorem. We apply this to p-adic families of such objects and in particular prove the existence of compatible families of sections of some Hecke correspondences on explicit tubular neighborhood of the ordinary locus in some PEL type Shimura varieties.
