I'm processing gravity data. i'd like to invert the grid by using voxi. Which grid must be used (free-air, bouguer, complete bouguer or anomaly?)

Since, for example, Bouguer Anomaly takes into account for free-air and slab correction, what must I use during the creation of the voxi (In the SURFACE ELEVATION (constant or dem)) and during the ADD DATA in the SENSOR ELEVATION menu?

    Hi Filippo, you can use either the Free Air or Bouguer Anomaly as input. Note that VOXI outputs a voxel of density relative to the background density. Therefore, if FAA is used density values are relative to 0 g/cc, if BA is used density values are relative to the terrain correction density.
