It’s a purely aesthetic error; it appears to have no impact on further processing.
I got that dataset - combined with an untilted dataset off the same grid - to 1.9 Ang, found some other interesting things they weren’t expecting; now just waiting for collaborators to move forward with the rest of the project… independently the two datasets got to 2.1 (tilted) and 2.2 but a bit anisotropic (for the untilted).
Plotting angles from the orientation distribution shows the alignments are more the angle expected than the one reported from the SR CTF tilt estimates, and comparing projections of the 3D vs. 2D they look dead on for 30 degree tilt projection.
