Let Λ1, Λ2 be two discrete orbits under the linear action of a lattice Γ < SL2(ℝ) on the Euclidean plane. We prove a Siegel–Veech-type integral formula for the averages
from which we derive new results for the set SM of holonomy vectors of saddle connections of a Veech surface M. This includes an eﬀective count for generic Borel sets with respect to linear transformations, and upper bounds on the number of pairs in SM with bounded determinant and on the number of pairs in SM with bounded distance. This last estimate is used in the appendix to prove that for almost every (?,ψ) ∈ S1 × S1 the translations ﬂows F?t and Fψt on any Veech surface M are disjoint.
