The Ricci curvature of Diff S1/SL(2, R)

Abstract
Previous calculations of the Ricci curvature for the manifold Diff Diff(S1)/S1 are extended to Diff(S1)/SL(2R ). These manifolds are distinguished by being coadjoint orbits of Diff(S1) which admit compatible symphectic and complex structures, making them Kähler manifolds.
