      stella.adapter.StellaGuider.ReduceThread

All Implemented Interfaces:

Runnable

Enclosing class:

StellaGuider

private class StellaGuider.ReduceThread
extends Thread

This thread does the reduction of CCD data to a level that a list of detected stars can be retrieved. It is intended for continuous operation only, thus allowing a new exposure to be taken while the old one is reduced.
