Fraction of the scattering cross sections of dGFP samples

Sample	Protein incoherent	Protein coherent	D2O incoherent	D2O coherent	% Intensity from in-phase motion at EBP
dGFP dry	15.1%	84.9%	0.0%	0.0%	32.6 ± 3.7% at 170 K
					34.3 ± 1.2% at 295 K
dGFP D2O h = 0.4	10.8%	60.5%	6.0%	22.6%	22.6 ± 3.5% at 170 K
					9.3 ± 4.1% at 295 K

The last column gives the percentage of scattering at the boson peak resulting from in-phase coherent motions of the secondary structure.
