This form enables you to generate a diagram showing the east-west motion of the inner satellites of Mars across the planet's disk. The distance of each selected moon from the planet's axis is plotted in units of either degrees or planetary radii. Positive values correspond to bodies on the "morning" side of the planet (moving toward the observer) and negative values by the "evening" side. In the diagram, the planetary limbs are indicated by a dark gray stripe down the middle. Time increases downward on the plot.
The Moon Tracker tool also allows you to download an ASCII table containing the numeric values that went into the diagram. The file contains a single header line followed by the numbers. Columns are as follows:
Interval: Enter the time interval to be used for the tabulation as a number in the box, and select the time unit from the choices provided. Start times and intervals are rounded to the nearest minute.
You may specify the point of view of the diagram. By default, the point of view is the center of the Earth.
Observatory: You may select from any viewpoint on the list.
Latitude & Longitude: If your desired observatory or location is not on the observatory list, you can enter its latitude, longitude and altitude in the three boxes provided. Latitudes and longitudes can each be specified by up to three values, interpreted as degrees, minutes and seconds. Longitudes can be specified either east or west.
If you wish to have an observatory added to the standard list, or to refine the coordinates of a listed observatory, email the necessary information to email@example.com.
Title: Enter a title for the plot in this box. It will appear centered above the diagram.
By default, when you click on "Submit", you are directed to a web page that lists the details of the request, a small preview of the diagram produced, and options to view or download that diagram as PDF, JPEG, Postscript, or as an ASCII table. Optionally, you can choose to bypass the web page and go directly to any one of these four formats.
