uvw_transform

ska_sdp_func_python.util.coordinate_support.uvw_transform(uvw, transform_matrix)[source]

Transforms UVW baseline coordinates such that the image is transformed with the given matrix. Will require kernels to be suitably transformed to work correctly.

Parameters:
  • uvw(u,v,w) distribution of projected baselines (in wavelengths)

  • transform_matrix – 2x2 matrix for image transformation

Returns:

New baseline coordinates
