Fit a single component to a visibility

Uses the scipy.optimize.minimize function.

Parameters:

  • vis – visibility

  • sc – Initial component

  • tol – Tolerance of fit

  • niter – Number of iterations

  • verbose –

  • method – ‘CG’, ‘BFGS’, ‘Powell’, ‘trust-ncg’, ‘trust-exact’, ‘trust-krylov’: default ‘trust-exact’

  • kwargs –

Returns:

SkyComponent, convergence info as a dictionary
