phi_gain_adj_pvec(pvec)
phi_gain_adj_roots(roots)
phi_native_rep_lnG(rB)	function mapping roots from native domain (S) to fit representation domain outputs both the remapped roots, as well as the lnG adjustment
phi_rep(F_Hz)	function mapping roots from frequency domain to fit domain
phi_rep_Snative(rB)	Maps the internal representation to Snative, the output RootBunch can have a specialty constraint added.
phi_rep_native_lnG(rB)	function mapping roots to native domain (S) from fit representation domain outputs both the remapped roots, as well as the lnG adjustment
poly_fromroots(roots)	Cleans the coefficients as well
root_BW_soften_Snative(root)
root_stabilize(rB[, method, real_neg, real_pos])
