All Implemented Interfaces:

TrueFitsStart, Cloneable, CoordinateTransforming, VectorFunction, PropertySupplying
```
public class AltAzFromFits
extends PropertyContainer
implements CoordinateTransforming, TrueFitsStart, VectorFunction
```
Transforms fits coordinates into azimuth/altitude. Based on chianti: /work2/wooz/stella/asiva/Coord_Transform_Processing_Tenerife_ASIVA.pro This class is a VectorFunction, where it directly transforms fits coordinates, starting from 1,1 to azimuth/altitude, both degrees. Additionally, it implements a coordinatetransforming instance. Measured are radius 262, center y more at 270

    azalt -
    
    Returns:
    
    The pixel coordinates in the fits file.
  - evaluate
```
public VectorG evaluate(VectorG xy)
```
    This is the core of the class, here we convert x/y in fits true space (starting from 1,1) to (astronomical) azimuth and altitude in degrees. Azimuth is zero in south, +90 in West. All other methods rely on this one.
    
    Specified by:
    
    evaluate in interface VectorFunction
    
    Returns:
    
    A Vector2D, astronomical azimuth at x, altitude in y, both degrees.
