  We investigate the continuum limit of the rooted staggered determinant in the
2-dimensional Schwinger model. We match both the unrooted and rooted staggered
determinant with an overlap fermion determinant of two (one) flavors and a
local pure gauge effective action by fitting the coefficients of the effective
action and the mass of the overlap operator. The residue of this fit measures
the difference of the staggered and overlap fermion actions. We show that this
residue scales at least as O(a^2), implying that any difference, be it local or
non-local, between the staggered and overlap actions becomes irrelevant in the
continuum limit. This observation justifies the rooting procedure.
