hera_sim.foregrounds.DiffuseForeground.__call__

DiffuseForeground.__call__(lsts, freqs, bl_vec, **kwargs)[source]

Compute the foregrounds.

Parameters:

  • lsts (array-like of float) – Array of LST values in units of radians.

  • freqs (array-like of float) – Array of frequency values in units of GHz.

  • bl_vec (array-like of float) – Length-3 array specifying the baseline vector in units of ns.

Returns:

vis (ndarray of complex) – Array of visibilities at each LST and frequency appropriate for the given sky temperature model, beam size model, and baseline vector. Returned in units of Jy with shape (lsts.size, freqs.size).
