All Implemented Interfaces:

GlobalDepending, Cloneable, CcdReference, Horizontal, RayPath, PropertySupplying

public class PrimeFocusGeometry
extends AbstractHorizontalGeometry
implements RayPath

In prime focus, the angle between the CCD-y axis and the elevation axis is fixed for an alt-az telescope. This is the alignment angle. The equatorial angle is this fixed angle plus the parallactic angle.

Method Detail

getEquatorialAngle

public Number getEquatorialAngle()

Description copied from interface: CcdReference

Returns the angle between the y-axis of the CCD and the declination axis. If the CCD has negative chirality, this is also the angle to the right-ascension axis.

Specified by:

getEquatorialAngle in interface CcdReference

getHorizontalAngle

public Number getHorizontalAngle()

Description copied from interface: CcdReference

Returns the angle between the y-axis of the CCD and the elevation axis. Refer also to the figure A. If the CCD has positive chirality, this is also the angle to the azimuth axis.

Specified by:

getHorizontalAngle in interface CcdReference
