(a, b, c) Examples of detector images showing ice diffraction. (a) Mixture of hexagonal ice (Ih) and stacking-disordered ice (Isd) in a glycerol-free apoferritin crystal at 230 K. (b) Isd in a glycerol-free apoferritin crystal at 180 K. (c) Isd in a glycerol-free thaumatin crystal at 200 K. (d, e, f) Dotted blue lines indicate azimuthally integrated and background-subtracted ice-ring diffraction profiles calculated from the detector images in (a), (b) and (c), respectively. The solid orange lines are best-fit profiles calculated using DIFFaX.
