ODL Stereo Frame Pairing Counter Offset
Per-file and per-session stereo timing from 4 days (957,332 frame pairs): left/right strobe-counter offset, exposure-start difference, counter-pairing error.

Visual evidence
Figures are taken from the released technical-note package. Interpret with the original methods and limitations.
Figure 1
Left − right strobe counter for each work session, coloured by day.
Figure 2
The same 957,332 frames under the two pairing rules. Pairs that the counter rule gets right (offset 0) fall below the left panel's range.
Figure 3
The same exposures carry different counter values in the two eyes. In this session the left counter is always the right counter plus 48.
Figure 4
Exposure-start difference of every order-based pair: the rig's true stereo synchronisation.
