Notes The product has the same format as the other lithospheric field models, but at a higher SH degree to be used for mapping purpose only. SH Gauss coefficients are here a mean to store the map, but the product itself is a map. The map should not be computed at altitudes lower than the minimum altitude of Swarm measurements
