Update GR5H interception grid-screening parameter quantiles
According to the tests made by @cyril.thebault on the ~579 catchments, it seems to be needed to update the GR5H interception parameter quantiles used during the grid-screening calibration step.
Current values:
GR5Hinterception = matrix(c(+3.46, -1.25, +4.04, -9.53, -9.34,
+3.74, -0.41, +4.78, -8.94, -3.33,
+4.29, +0.16, +5.39, -7.39, +3.33), ncol = 5, byrow = TRUE)
New values (found after 4 convergence loops):
GR5Hinterception = matrix(c(+4.92, -0.17, +4.27, -9.81, -9.29,
+5.42, -0.07, +4.94, -9.66, -7.36,
+6.05, -0.01, +5.63, -9.26, -5.55), ncol = 5, byrow = TRUE)
