• Production

Latitudes where a fixed star and a planet are angular at the same moment, which is how Brady tabulates a paran: not a place, a latitude. Twelve event pairs per star and planet (rise, set, culminate, anticulminate, minus meridian against meridian, which is a shared right ascension rather than a paran). Each row carries the houses of the technique in plain form: which body does what, the latitude, and the meridian where it happens at this chart moment. Solved on hour angles rather than by intersecting map polylines, so the latitude is exact rather than quantised to the polyline step. horizon selects the geometric horizon (default) or the apparent one at -34 arcmin, measured at about two degrees of paran latitude at mid-latitudes.

Request Body ^required

Media type application/json

Birth data for star-planet parans. Coordinates are not used: a paran is a latitude, and which latitudes exist depends on the moment, not on where the native was born.

Swiss Ephemeris planet ids. Default: 0-9, Sun through Pluto.

latitudeLimit

Search range either side of the equator, degrees. Default 60, which is the range Brady tabulates.

number

horizon

Which horizon counts as rising. geometric (default) is altitude 0, the semi-diurnal arc as written in Meeus. apparent puts it at -34 arcmin, where refraction lifts a body into view first. Worth about two degrees of paran latitude at mid-latitudes, and refraction also breaks the equator mirror that the geometric horizon has, so it is a choice rather than a detail.
