AUTHORS STATE THAT REMARK 3 ALTHOUGH HYDROGENS CANNOT BE VISUALIZED AT THIS RESOLUTION, THEY REMARK 3 ARE PRESENT AND CONTRIBUTE TO SCATTERING. THE HYDROGENS ARE KEPT REMARK 3 IN THIS ENTRY BECAUSE INDEPENDENT ASSESSMENT OF MANY ASPECTS OF REMARK 3 THE GEOMETRY, INCLUDING STERIC CLASHES, REQUIRE THEIR PRESENCE. REMARK 3 MOREOVER, REMOVING HYDROGEN ATOMS AFTER REFINEMENT MAKES REMARK 3 INDEPENDENT ASSESSMENT OF REFINEMENT STATISTICS EFFECTIVELY REMARK 3 IRREPRODUCIBLE.
