Imum Coeli Lines
IC lines connect locations where a selected natal body was anti-culminating on the lower meridian at birth. Scope is explicit.
Overview
L belongs to the Moon/IC meridian condition. This is the worked result for Imum Coeli Lines; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Choose one body, solve the lower-meridian anti-culmination opposite the upper transit, label its IC curve, and compare the same place’s relocation chart.

Definition and exact scope
IC lines connect locations where a selected natal body was anti-culminating on the lower meridian at birth. The lower transit lies opposite the same body’s MC condition and must retain the IC label rather than being merged into culmination.
Calculation or decision rule
Choose one body, solve the lower-meridian anti-culmination opposite the upper transit, label its IC curve, and compare the same place’s relocation chart. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Worked case and illustrative near miss
at the birth instant, ☽ hour angle 180° and lower culmination at longitude L. L belongs to the Moon/IC meridian condition.
Illustrative near miss; does not qualify: Calling an upper culmination Moon/IC because both are drawn on one meridian.
School, model, and context variants
A IC curve cannot guarantee a permanent home, family outcome, property gain, or emotional rootedness; its body label, natal condition, map precision, and practical place evidence remain required.
