Synastry

Two natal charts side by side from two sets of birth data: inter-aspects, an aspect grid, house overlays, the composite (midpoint) chart and the Davison (time–space midpoint) chart, as numbers.

Not a reading; no scoring or weighting. Positions come from the same code as Positions; orbs as in the main reading.

CSV is UTF-8 with BOM (column names in Japanese). Saved data stays on this device (localStorage). “From saved inputs” lists inputs saved in the Positions tool.

Positions as in the Positions tool (JPL Horizons tables, Astronomy Engine, Meeus). The composite uses longitude midpoints; the Davison chart is cast for the midpoint in time and place.
