Note that the time limits actually used are rounded off to be exact multiples of the chosen interval. Plot Scale Enter the numeric range and units of the horizontal axis. Zero always falls at the middle of the plot. Moon Selection Click on the box to the left of each moon that you wish to include in the diagram and in the tabulation. Ring Selection Click on the box to the left of each ring that you wish to include in the diagram.

For plotting purposes, the rings are shown extending all the way down to the planet. Currently, the Jupiter Moon Tracker can use one of two different ephemerides. Under most circumstances the last option is to be preferred since it is most recent and therefore most accurate. It uses JPL ephemerides JUP071, JUP066 and JUP067. It uses JPL ephemerides JUP100 for the Galilean satellites and JUP104 for the inner, smaller satellites.
