Gauge Length

[vkazei]

Hi Haipeng,

Where is actual averaging happening? Do you look up the ends of the GL segment?
"""

pull the model to the data space

        d[ic, :] = (np.dot(self.tangent[channl_pos], m[:, channl_pos_lookup, :]) -
                    np.dot(self.tangent[channl_neg], m[:, channl_neg_lookup, :]))

    # average the data over the gauge length
    d /= self.gauge_len

"""
Is any GL applied in the Marmousi baseline example?

Best,
Vladimir
