Figure 4
Experimental data (solid circles) for integrated intensity in resolution shells versus dose for crystals of insulin, P19 and FAE at 100 K, as measured by Bourenkov & Popov (2010) (Figs. 3, 4 and 6 in the original paper). Crystals were rotated continuously during irradiation as for crystallographic data collection. Oscillations in the data may be owing to irregular crystal shapes and large rotations that produce complex dose distributions within the X-ray-illuminated volume. The solid lines indicate the results from simulations with best-fit exponents α of (a) 1.4, (b) 1.6 and (c) 1.8. |
