+These parameter sets can be used for the grid-screening calibration procedure.
 Please NOTE that the given GR4J X4u variable does not correspond to the actual GR4J X4 parameter.
 As explained in Andréassian \emph{et al.} (2014; section 2.1), the given GR4J X4u value has to be adjusted (rescaled) using catchment area (S) [km2] as follows: {X4 = X4u * S^0.3}.
 Please, see the example below.
