Discussion: On '3-D inversion of gravity and magnetic data with depth resolution'

摘要

the upward-continued data at different heights do not improve the depth resolution of the gravity or magnetic inversion. Any resolution improvement can only come from the use of prior information about the distribution of the density contrast or the magnetization. One form of prior information is the restriction on the geometry of the distribution. What the paper by Fedi and Rapolla has illustrated is the effect of adding prior information, not the effect of adding upward-continued data.
