StaticMatrixTransform
(matrix, fromsys, tosys, priority=1, register_graph=None)[source]¶ Bases:
astropy.coordinates.BaseAffineTransform
A coordinate transformation defined as a 3 x 3 cartesian transformation matrix.
This is distinct from DynamicMatrixTransform in that this kind of matrix is independent of frame attributes. That is, it depends only on the class of the frame.
Parameters:  matrix : arraylike or callable
A 3 x 3 matrix for transforming 3vectors. In most cases will be unitary (although this is not strictly required). If a callable, will be called with no arguments to get the matrix.
 fromsys : class
The coordinate frame class to start from.
 tosys : class
The coordinate frame class to transform into.
 priority : number
The priority if this transform when finding the shortest coordinate transform path  large numbers are lower priorities.
 register_graph :
TransformGraph
orNone
A graph to register this transformation with on creation, or
None
to leave it unregistered.
Raises:  ValueError
If the matrix is not 3 x 3
