Cohomologial dimension of Laumon 1-motives up to isogenies

We prove that the category of Laumon 1-motives up to isogenies over a field of characteristic zero is of cohomological dimension 1 . As a consequence this implies the same result for the category of formal Hodge structures of level 1 (over ).
