a Australian magnetic anomaly grid from the combined low-pass-filtered fourth and fifth editions; b near-surface and satellite vector observations used in this study include the low-pass-filtered Australian fifth edition magnetic grid values at a 0.25° interval (red dots), the low-pass-filtered fourth edition of magnetic grid values at a 0.25° interval (green dots), and the selected CHAMP satellite vector component observations (blue dots) from the final 2 years of mission. See Table 3 for the statistics of the magnetic anomaly maps produced in this and the other figures of this study
