System Context
Fig:sysCtxDiag shows the system context. A circle represents an entity external to the software, the user in this case. A rectangle represents the software system itself (BSS). Arrows are used to show the data flow between the system and its environment.

The interaction between the product and the user is through an application programming interface. The responsibilities of the user and the system are as follows:
- User Responsibilities
- Provide the physical parameters of the binary star system, including stellar masses, initial positions, and initial velocities, ensuring no errors in the data entry.
- Ensure that consistent units are used for inputs.
- Ensure required software assumptions are appropriate for any particular problem input to the software.
- BSS Responsibilities
- Detect data type mismatch, such as a string of characters input instead of a floating point number.
- Determine if the inputs satisfy the required physical and software constraints.
- Calculate the required outputs.
