The obtained formula is the same as that for Fuchs-Kroyter-Potting/Kiermaier-Okawa's marginal solution, which was already computed by Ellwood. Our result is consistent with the expectation that they may be gauge equivalent. We also comment on a gauge invariant overlap for rolling tachyon solutions in cubic open string field theory.12 pages; v2:typos corrected, a reference added; v3:PTPTeXHigh Energy Physics - Theorytext
