Figure 2 (A) Diffraction image (0.25° oscillation) of a cryoprotected Head II tetragonal crystal. (B) Zoomed view of an area corresponding to 4.2 Å resolution. (C) Zoomed view of five reflections. This crystal measured 0.4 mm × 0.4 mm × 0.15 mm and was exposed for 20 s to the unattenuated convergently focused beam of GM/CA CAT's 23-ID-D beamline. The image was recorded on a Mar225 during the 2005 beamline commissioning phase.
