Member Function Documentation

double GnomonicProjector::cosMaxFieldAngle ( ) const

virtual

This function returns the cosine of the maximum field angle, i.e., the maximum angular distance from the focus for which a point should be projected.

Default is 0, i.e., 90 degrees.

Reimplemented from Projector.

Definition at line 49 of file gnomonicprojector.cpp.

double GnomonicProjector::projectionK ( double  x ) const

virtual

This function handles some of the projection-specific code.

double GnomonicProjector::projectionL ( double  x ) const

virtual

This function handles some of the projection-specific code.

double GnomonicProjector::radius ( ) const

virtual

Get the radius of this projection's sky circle.

Returns

the radius in radians

Reimplemented from Projector.

SkyMap::Projection GnomonicProjector::type ( ) const

virtual

Return the type of this projection.

Implements Projector.
