    Sets the hour angle of the actual target. This is a read-only variable, therefore this method throws an UnsupportedOperationException.

    Throws:
    
    UnsupportedOperationException
  - registerTarget

    Registers a star to this parameter. The target definition is directly passed to the ra reference of this parameter. Note that this will set the target in the additional parameter, too.

```
    Registers the required additional globals for the tau target. For this particular object, loacal sidereal time and target ra are required. Note that the argumental global is checked for being of instance types of SiderealTime or RaTarget, rather than querrying for the global name.
