All Implemented Interfaces:

Cloneable, PropertySupplying
```
public class GuidingStatistic
extends PropertyContainer
```
A class that reads serialized guider-offset files and produces statistic information out of it. The input file must have a minimum number of data points KEY_MINLENGTH to be considered. If that is the case, the data in both axes is fit to a straight line. If the slope and the offset of these lines are below KEY_MAXOFFSET KEY_MAXSLOPE, the residuals to the line fits are used to calculate an RMS of the image motion in azimuth, altitude, and, using the combined fits, in total. The exposure time plus the seeing and wind information in the guider file is then used to create artifical expected image motion from seeing effects. The RMS of this is calculated and printed out together with the wind-speed, the seeing and the measured RMSs.
