The same twelve rows as positions(), at progressedInstant(birthUtc, target):
Sun, Moon, eight planets and the true north/south lunar nodes. Speed remains
the ephemeris rate in degrees per day at that instant, a central difference
over ±0.001 day (±0.25 day for the nodes); numerically it is also degrees
per tropical year of life, not degrees per lived day. An instant the
ephemeris cannot evaluate throws RangeError. No progressed angles, houses,
chart points or receipt are calculated.
