calculate_image_from_frequency_taylor_terms

ska_sdp_func_python.image.taylor_terms.calculate_image_from_frequency_taylor_terms(im: Image, taylor_terms_image: Image, reference_frequency=None) → Image[source]

Calculate channel image from Taylor term expansion in frequency.

\[w_k = \left(\left(\nu - \nu_{ref}\right) / \nu_{ref}\right)^k\]

Note that a new Image is created.

The Taylor term representation can be generated using MSMFS in deconvolve.

Parameters:

  • im – Image cube to be reconstructed

  • taylor_terms_image – Taylor terms cube

  • reference_frequency – Reference frequency (default None uses average)

Returns:

Reconstructed Image
