- Catalog epoch
- Per-planet reference time of conjunction or periastron (facts.ephemeris_reference_time_jd, facts.ephemeris_time_system)
- Position epoch
- Selected atlas UTC time, as the phase that an observer in the Solar System sees; light travel time is not removed
- Selection caveat
- Orbit size and timing come from the archive. The orbit direction around the line of sight is a display convention, not a measurement. Period and reference time come from one paper where the archive has such a row; mixed values carry a flag. Transit timing variations, the time system, and the argument-of-periastron convention of each paper can move the true phase.
