Detailed Description

SpatialVector is a 3D vector usually living on the surface of the sphere.

The corresponding ra, dec can be obtained if the vector has unit length. That can be ensured with the normalize() function.

Constructor & Destructor Documentation

SpatialVector() [1/3]

SpatialVector::SpatialVector

(

)

constructs (1,0,0), ra=0, dec=0.

Definition at line 29 of file SpatialVector.cpp.

SpatialVector() [2/3]

SpatialVector::SpatialVector	(	float64	x,
		float64	y,
		float64	z )

Constructor from three coordinates, not necessarily normed to 1.

Definition at line 33 of file SpatialVector.cpp.

SpatialVector() [3/3]

SpatialVector::SpatialVector	(	float64	ra,
		float64	dec )

Constructor from ra/dec, this is always normed to 1.

Definition at line 39 of file SpatialVector.cpp.

Member Function Documentation

dec()

float64 SpatialVector::dec

(

)

return dec - this norms the vector to 1 if not already done so

Definition at line 96 of file SpatialVector.cpp.

get() [1/2]

void SpatialVector::get	(	float64 &	ra,
		float64 &	dec )

Get ra,dec - normalizes x,y,z.

Definition at line 75 of file SpatialVector.cpp.

get() [2/2]

void SpatialVector::get	(	float64 &	x,
		float64 &	y,
		float64 &	z ) const

Get x,y,z.

Definition at line 66 of file SpatialVector.cpp.
