find_skycomponents_frequency_taylor_terms

ska_sdp_func_python.sky_component.taylor_terms.find_skycomponents_frequency_taylor_terms(dirty_list: List[Image], nmoment=1, reference_frequency=None, **kwargs) → List[List[SkyComponent]][source]

Find skycomponents by fitting to moment0, fit polynomial in frequency, return in frequency space.

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

  • dirty_list – List of images to be searched. These should be different frequencies

  • nmoment – Number of moments to be fitted

  • reference_frequency – Reference frequency (default None uses centre frequency)

Returns:

List of SkyComponents
