Time series of selected Gauss coefficients from CHAOS-6 (solid red), those hindcast with \(L_u = 14\) and \(N = 0\) (dashed black), with \(L_u=14\) and \(N = 2\) (dotted blue), and with the SV prescribed by IGRF-11 (dot-dashed green). The 2009.0–2010.0 model fitting period was used. A comparison to the linear extrapolation of IGRF-11 and a CHAOS-3 forecast are also shown
