This attribute lets you select the coordinate system to be used by a stopping condition.
Astrogator <Satellite Object Path> SetValue <Attribute Path>.StoppingConditions.{Stopping Condition}.CalcObjectAttributes.CoordSystem {Value}
This attribute is interchangeable with the CentralBody and ReferencePoint attributes. It is used only for stopping conditions that take the coordinate system into account (e.g., Argument of Latitude). The default coordinate system of a stopping condition is Earth Inertial. The value can be any coordinate system listed in the Select Reference Axes window of the Component Browser. If you require additional coordinate systems, you can define them using the Vector Geometry Tool. Make certain that the name is copied exactly and that spaces are replaced by underscores. In addition, the coordinate system name must be preceded by the class name (for example, CentralBody) and a forward slash "/".
