User Manual

GENTLEMAN may be used very quickly via its GUI facilitating context elaboration and results exploitation. No code knowledge is necessary. It is also possible to use it in batch mode via a shell and especially on grid computers with no display properties. On the other hand, it is also possible to use it via its Java interface inside a higher level tool (for example, an orbit determination tool or a maneuver optimization tool).

So, three jar files are available:

• gentleman-NN.n-jar-with-dependencies.jar : executable jar including all needed libraries => it is the file to use for GUI utilization but it may also be used for the Java interface
• gentleman-NN.n.jar : includes only GENTLEMAN classes => to be used for Java interface, under the condition of linking with the right version of [GENOPUS], [PATRIUS], etc.
• gentleman-NN.n-javadoc.jar
