    Function birthWindow

    • Partition a birth-time window, [start, end) of at most 48 hours inside REFERENCE_SPAN, into cells within which each body's sign and house, the signs of the ascendant and midheaven, the aspects in orb and any Placidus or Koch fallback are constant. Values are the engine's own at each millisecond, as a lone natalChart call computes them. Where the search's bounds hold (README), each cell holds natalChart's features at every millisecond, except the nodes' in the intervals listed in unresolved, which are null. Labelled WINDOW_VERIFICATION: checked against dense sampling, not proven. Throws RangeError for invalid input, and WindowBudgetError, which is not a RangeError, when the search would need more than two million instants.

      Parameters

      Returns BirthWindow
