spacecraftErrorKmfunction

The worst error of a craft's loaded path against Horizons, in kilometres, as measured when it was made: on samples held back from the fit and on fresh samples at random times. It grows with the craft's distance from the Sun (a millionth of it in cruise), and is 1,000 km or better near a planet.
