Height on families of Abelian varieties

Let $X$ be an Abelian variety imbedded in projective space, and let $L$ be an induced invertible sheaf on $X$.
In this paper explicit bounds are determined for the difference $\widehat h_L-h_L$, where $\widehat h_L$ is the Neron–Tate height and $h_L$ is the Weil height.
