How it is measured
The position of the spacecraft relative to the body is read from Horizons every minute for six hours around the approach, then every second for three minutes around the nearest minute. The closest of those positions is the one published here.
Horizons does not serve this body as a centre: the position is the difference of the two positions it serves relative to the Sun.
