Crossover adjustment of ship-borne gravity data using x2sys package

Hello, I have some tracks data files of ship-borne gravity in geographic coordinates and i need to crossover adjust these data using x2sys package but I don’t know how to start.
any help please.

The best help you can get right now is to study the documentation.

Also helpful will be Paul’s paper describing the package and possibly the test scripts that reproduce the figures in the paper which are in the test directory of the GMT repository.
