Compute the visbilities using the SWHT

Compute the visbilities using ths Spherical Wave Harmonic Transform It is a reverse method of the one presented in T.Carozzi 2015

Parameters:

  • b (Quantity [m]) – Baselines of the interferometer with the shape (Nbaseline, 3)

  • shcoeff (SHCoeff) – Map class that holds the Spherical Harmonic Coefficients of the skymap

  • freq (Quantity [Hz]) – Frequency of the observation (a scalar)

  • lmax (int or None, optional) – _description_, by default None

Returns:

Set of Visibilities with shape (Nbaseline,) in Jansky

Return type:

Quantity [Jy]
