Total signal and rmsd are given in units of fringe displacement. The refractive index increment dn/dc* is calculated from the total signal after subtraction of non-proteinaceous LMW material as an indication of mass retrieval. Relative contents of monomer and dimer+oligomers are calculated excluding the signal contribution of LMW material.
