get_SED_log_par_fit

get_SED_log_par_fit(x_p, y_p, j, comp, delta_p=[-1, 1])

log-parabolic fit of a jet SED spectral component

Parameters:

• x_p (starting value (log)) –

• y_p (starting value (log)) –

• j (jet object) –

• comp –

• delta_p (+/- boundaries centered on x_p fit range (log of nu in Hz), i.e. fit rage= [log10(nu_p) + delta_p[0], nu_p + log10(delta_p[1]) ]) –

Returns:

• p [x_p, y_p, curvature]

• err [err x_p, err y_p, err curvature]
