public class PointingModelPivot
extends PinholePivot
implements GlobalDepending
```
Basic pointing model that shows only a dependency of altitude. Model for a differential pointing model between auxiliar and main telescope. The minimum zero point of the elevation the pointing model was derived with is stated in elzero. Thus, trigonomertic functions are normalized to the mean of the observable cap via the definite integral F_j=∫∫F(az,el)dΩ/∫∫dΩ where the integral spans normally 0 to 2*π in azimuth and in height elzero to &pi/2, thus returning for the denominator ∫∫dΩ = 2*π*(1-sin(elzero); The nominators for the two trigonometric function ised in this simple model, i.e. for sin(h) and cos(h) read as 2*π*0.25*(1+cos(2*elzero)) for sin(h) 2*π*(π/4-elzero/2-.025*sin(2*elzero)) for cos(h) If done properly, no constant coefficients are needed, they are the rotation center of the guider CCD.
