 ## ARGO Alignment Examples
 
 ARGO profiles are projected onto the fixed 50-level GLORYS depth axis before
-spatial rasterization. The examples below show the grid-indexed ARGO
+spatial rasterization. Please not that the ARGO-derived temperature value is 'measured', not 'potential'. The examples below show the grid-indexed ARGO
 representation and profile-level alignment quality.
