	A better profile for Vp at shallow depths could be obtained by adding a supplementary layer on Vp profile like on Vs profile. On one hand, a variation in Vp is not to exclude especially in superficial layers at the level of the water table in soft sediments. However we have no clues from the dispersion itself that such a layer can exist. On the other hand, the uncertainty of Vp close to the surface is likely to have some contributions in the uncertainty of Vs at depth. Hence playing with [[#Vp paramterization\|Vp parameterization]] might be of interest.
