All fast EBEC tilt series were indexed with XDS, allowing refinements to orientation, unit cell, direct beam position, and rotation axis in the IDXREF and CORRECT steps, and direct beam position and orientation in the INTEGRATE step. All such refinements were performed over batches of images encompassing 5 degrees of rotation. A high resolution limit of 0.8 Angstroms was enforced for integration. Data was scaled in XSCALE, and data reduction statistics were recorded from the scaling output.
