| midpoints | object | Calculated midpoints between planet pairs |
| omitted_bodies | arraynull | Bodies that were requested (or are in the chosen object_set/asteroid_groups) but not computed because the chart date is outside the span of their own JPL kernel. Absent when nothing was omitted. Each |
| patterns_by_type | object | Patterns organized by type for easier filtering |
