    fetchPosition in class ParticleGroup
    
    Parameters:
    
    pb - The particle bean

    destination - The destination factor
    
    deltaYears - The delta years
    
    Returns:
    
    The vector for chaining
  - getDeltaYears
```
protected double getDeltaYears()
```
    Description copied from class: ParticleGroup
    
    Returns the delta years to integrate the proper motion.

    getDeltaYears in class ParticleGroup
    
    Returns:
  - setEpoch
```
public void setEpoch(java.lang.Double epochJd)

  - getEpoch
```
public java.lang.Double getEpoch()
```
    Returns the epoch in Julian Days used for the stars in this group
    
    Returns:
    
    The epoch in julian days
  - dispose
```

    Overrides:
    
    dispose in class ParticleGroup
  - getColor
```
public float getColor(int index)
```
  - getStarGroup
```
public static StarGroup getStarGroup(java.lang.String name,
                                     java.util.List<ParticleGroup.ParticleBean> data,
                                     DatasetOptions dops)
```
    Creates a default star group with some parameters, given the name and data
    
    Parameters:
    
    name - The name of the star group. Any occurrence of '%%SGID%%' will be replaced with the id of the star group
    
    data - The data of the star group
    
    dops - The dataset options
    
    Returns:
    
    A new star group with the given parameters
  - getDefaultStarGroup
```

                                            java.util.List<ParticleGroup.ParticleBean> data)
```
    Creates a default star group with some sane parameters, given the name and the data
    
    Parameters:
    
    name - The name of the star group. Any occurrence of '%%SGID%%' in name will be replaced with the id of the star group
    
    data - The data of the star group
    
    Returns:
    
    A new star group with sane parameters
  - getDefaultStarGroup
```
public static StarGroup getDefaultStarGroup(java.lang.String name,

    data - The data of the star group
    
    fullInit - Initializes the group right away
    
    Returns:
    
    A new star group with sane parameters
  - updateMetadata
```
public void updateMetadata(ITimeFrameProvider time,
                           ICamera camera)
```
    Updates the additional information array, to use for sorting. In stars, we need to take into account the proper motion and the brightness.
    
    Overrides:
    
    updateMetadata in class ParticleGroup
    
    Parameters:
    
    time - The current time frame provider
    
    camera - The camera
