Class NasmythFocusGeometry

java.lang.Object

util.PropertyContainer

stella.acquire.AbstractHorizontalGeometry

stella.acquire.NasmythFocusGeometry

All Implemented Interfaces:

GlobalDepending, Cloneable, CcdReference, Horizontal, RayPath, PropertySupplying

public class NasmythFocusGeometry
extends AbstractHorizontalGeometry
implements RayPath

In the Nasmyth focus, the angle between the CCD-y axis and the elevation axis depends on the target height, sign depending on the mount port. Accordingly, the angle between the equatorial system and the CCD system does not only depend on the parallactic angle, but also on the target height.

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
