public class GuiderParametersAltAz
extends PropertyContainer
```
A class to optimize the parameter settings in the stella guider class. It is used with a list of input stars, given with their right ascension and declination and a set of x-y coordinates as derived from an actual guider image (use something like Sextractor to get CCD pixel coordinates). The set of stellar coordinates must match the set of x/y pixels in a sense that each star given in the position list is also found on the CCD. If we have at least two stars visible, this program optimizes for four parameters, the shift of the center of the CCD (xs, ys), the field rotation θ and the combined product of focal length and pixel scale on the CCD, f. If total reflection is in effect, you can include that by setting #KEY_MIRRORX or #KEY_MIRRORY to true.
Though θ and the focal length/pixel scale are in principle known, we optimize for these parameter, too.
