-All physical parameters used by the code are non-dimensionalized according
-to the conventions summarized in Table~{\small \ref{table:conventions}.
+All physical parameters used are non-dimensionalized internally in the code
+in order to work in a reference Earth of radius 1. In Table~{\small \ref{table:conventions} in the right column are the values by which 
+we divide the parameters of the left column internally to perform the calculations.
+The values output and saved by the code (seismograms, sensitivity kernels...) are then
+scaled back to the right physical dimensions before being saved.
