The initial and final Cartesian variational variables that describe an STM element.
| Member | Value | Description |
|---|---|---|
| eVASTMPertVariablePosX | 0 | Designates the initial or final variation in the 'x' component of position. |
| eVASTMPertVariablePosY | 1 | Designates the initial or final variation in the 'y' component of position. |
| eVASTMPertVariablePosZ | 2 | Designates the initial or final variation in the 'z' component of position. |
| eVASTMPertVariableVelX | 3 | Designates the initial or final variation in the 'x' component of velocity. |
| eVASTMPertVariableVelY | 4 | Designates the initial or final variation in the 'y' component of velocity. |
| eVASTMPertVariableVelZ | 5 | Designates the initial or final variation in the 'z' component of velocity. |
