Combined Data and Model Residuals

To compute the optimal set of 34#34, a quadratic objective function, 37#37, consisting of sum of the weighted norms of a data residual [equation ()] and of two model residuals [equations () and ()], is minimized via a conjugate gradient scheme:  

 38#38 (13)

39#39 and 40#40 are scalars which balance the relative weight of the two model residuals with the data residual.
