```
public class DSSTTesseralContext
extends DSSTGravityContext
```
This class is a container for the common parameters used in DSSTTesseral.
It performs parameters initialization at each integration step for the Tesseral contribution to the central body gravitational perturbation.

- Method Detail
  - getE2
```
public double getE2()
```
    Get ecc².
    
    Returns:
    
    e2
  - getTheta
```
public double getTheta()
```
    Get Central body rotation angle θ.
    
    Returns:
    
    theta
  - getMoa
```
@Deprecated
public double getMoa()
```
    Deprecated.
    since 12.2 Use getMuoa() instead
    
    Get μ / a .
    
    Returns:
    
    moa
  - getOrbitPeriod
```
public double getOrbitPeriod()
```
    Get the Keplerian period.
    The Keplerian period is computed directly from semi major axis and central acceleration constant.
    
    Returns:
    
    Keplerian period in seconds, or positive infinity for hyperbolic orbits
  - getRatio
```
public double getRatio()
```
    Get the ratio of satellite period to central body rotation period.
    
    Returns:
    
    ratio
