Abstract
It was recently shown by Aka, Einsiedler and Shapira that if
$d>2$
, the set of primitive vectors on large spheres when projected to the
$(d-1)$
-dimensional sphere coupled with the shape of the lattice in their orthogonal complement equidistribute in the product space of the sphere with the space of shapes of
$(d-1)$
-dimensional lattices. Specifically, for
$d=3,4,5$
some congruence conditions are assumed. By using recent advances in the theory of unipotent flows, we effectivize the dynamical proof to remove those conditions for
$d=4,5$
. It also follows that equidistribution takes place with a polynomial error term with respect to the length of the primitive points.
