Table A.1
Range offset measurements for Willner et al. (2014) and Ernst et al. (2023) shape models. The corresponding offsets of Phobos along its track are calculated using the method discussed in section 4. The longitude and latitude values are taken for the central point of the trajectory. The time reference is also taken for the central point, and is discussed in more detail in Appendix B.
| Orbit No | Encounter time UTC | Central longitude (°) | Central latitude (°) | Range offset (Willner) (km) | Range offset (Ernst) (km) | Phobos along-track offset (Willner) (km) | Phobos along-track offset (Ernst) (km) | Phobos propagated error along-track (km) |
