Claim One:
1. A scientific method for transforming seismic data into a subsurface physical property model, comprising: constructing the subsurface physical property model by performing tomographic inversion of the seismic data, using a computer, with residual depth errors reconstructed using property scanning; wherein the residual depth errors are reconstructed using the following relationship at each imaging point 
 DA ( v m −v f ) where A is a matrix built from ray tracing, v m is a base migration model of the property, v f is a model of the property as picked from a property scan of migrated seismic data, and deviation operator D is defined by its operation on an arbitrary n-dimensional vector a={a j }: ( Da ) j = a j - ∑ i a i n where indices i and j denote different source-receiver offsets among a total of n offsets present in the migrated seismic data.
