Forecasts of how ln H(ln Ha) Chebyshev expansions will do with Planck 2.5 year datasets using order 10 as an example cheb used instead of A_s, r_ts, alpha_s, n_s to describe the inflation dynamics for planck2.5yr 100 and 143 GHz data, With a chebyshev expansion of lnH to order 10, with other cosmic parameters fixed: of 10 cheb coeffs, 10 determined to 10%, 5 to 1% accuracy cheb + 5 cosmic params (4 abundances and the Compton depth): of 15 all to 10%, 10 to 1% (includes one fixed) 9 cosmic params, A_s, r_ts, alpha_s, n_s in place of the Chebyshev coefficients: of 9 all to 10%, 7 to 1% result of this limited study: omb, omc, omv omnu errors are similar, tauC a little higher. one reason is that there is not much complexity in the cheb in the high L region where omega_b etc are concentrated. Polarization information helps to break degeneracies as well.
