  We construct analytic solutions of open superstring field theory for any
exactly marginal deformation in any boundary superconformal field theory when
properly renormalized operator products of the marginal operator are given. Our
construction is an extension of the general framework for marginal deformations
developed in arXiv:0707.4472 for open bosonic string field theory, and the
solutions are based on integrated vertex operators which are closely related to
finite deformations in boundary superconformal field theory.
