This form enables you to generate a Postscript file showing the east-west motion of Neptune's satellites within a specified time period. The distance of each selected moon from the planet's axis is plotted in units of either arcsec or Neptune radii. In the diagram, the limbs of Neptune are indicated by a dark gray stripe down the middle. The location of the Adams Ring can be added as a band in lighter gray.
Time increases downward on the plot.
The file contains a single header line followed by the numbers. Original Neptune Moon Tracker on line. Revised user interface. Extended ephemeris time limits. Added new ephemeris option.
