Condition Grids
Condition Grids: For magnetic data, the grids are conditioned by centring (mean=0). For radiometric data the grids are centred, and scaled to unit standard deviation. Grids are read from the input directory, conditioned, and written to the output directory. Grid conditioning is not an essential process. However, it is useful when a large number of grids are being levelled, as it helps prevent rounding errors from compromising the inversions.
The aliases and parameters that must be set for this process (via the Set Aliases and Parameters menu) are shown in the table below.
