The point follows from the eastern horizon and ecliptic at a specified instant. Its calculation is sensitive to birth time and location; associations with identity are a separate interpretive step.

The point is geometrically opposite the Ascendant in the same chart frame. Its connection with partnership is traditional symbolism, not a measurement of another person or relationship quality.

The usual construction spaces boundaries thirty degrees from the Ascendant. This makes cusp arithmetic simple, but does not prove that equal sectors correspond to equal or measurable life influences.

House systems partition a chart by different geometric rules and assign topics to those divisions. A precise cusp calculation validates that chosen construction, not the universal truth of its life-topic assignments.

A cusp is reproducible only after a house method is chosen. A planet can change house when the method changes without changing its sky position; boundary proximity should be reported explicitly.

This point is fixed by opposition to the Midheaven. Associations with home and roots belong to astrological interpretation; the computed angle does not establish facts about someone’s family.

Koch uses its own time-based house construction. Its high-latitude limits are mathematical constraints, not evidence that a person lacks the life topics assigned to unavailable houses.

The meridian–ecliptic intersection is computable from time and place. Its vocational symbolism and its relationship to the tenth house depend on the interpretive and house conventions selected.

A birth record and calculation conventions produce a reproducible chart. Uncertain time or place limits its angular precision, while personality and life-event readings require evidence beyond correctly plotted positions.

The method derives cusps through time-based divisions of diurnal motion. Some high-latitude configurations lack solutions; substituting another method without disclosure changes the chart’s stated construction.

These methods share the four angles but divide the spaces between them differently. Shared endpoints do not make their intermediate cusps interchangeable or establish one universal set of house positions.

House assignment follows the Ascendant’s sign and a twelve-sign count. Its reproducibility comes from the rule; agreement within that rule does not demonstrate superiority over other house conventions.
