Direct Known Subclasses:

StarMatchedSextractor
```
public class SextractorStar
extends SimpleStar
```
Star description derived out of sextractor output. Has no color information or proper motion, but provides x and y location on the CCD (via getCcdX() and getCcdY() and a magnitude error. via getMagErr(). Usually, also the flags are retrievable getFlags() , the FWHM of the stellar image on the CCD in pixel ($getFwhm), and the ellipticity of the image getEllipticity().
A helper application that reads sextractor output files and parses them into a list of StarSextractor is SextractorRead, additional comparators for sorting are inner classes to this class.
