PTCOR pointing correction, and a selection of observed planet position offsets after applying the correction. Top: cross-scan pointing offset. This angle is directly affected by the second tilt angle, ψ₂, discussed in Fig. 3. Bottom: in-scan pointing offset. This angle corresponds to the spin phase and matches the third satellite tilt angle, ψ₃. Since ψ₃ is poorly resolved by standard attitude reconstruction, the in-scan pointing was already driven by PTCOR in the 2013 release.
