 Dear CCLers!
Could someone kindly help me and provide proper citation for the paper
 introducing
 the "RI-JK" resolution-of-identity algorithm in the form as
 it is
 implemented in Orca 2.9 ?
 My own findings are:
 a) F. Weigend, Phys. Chem. Chem. Phys. 4, 4285 (2002),
 b) Neese F., J. Comp. Chem., 24, 1740–1747 (2003),
 c) S. Kossmann and F. Neese, Chem. Phys. Lett. 481, 240 (2009),
but I'm not sure that any of these papers describe _exactly_ the
 algorithm used in Orca.
 Thank you in advance!
 Yours sincerely
 Tymofii
