The data-space residuals of the inversion schemes are presented in
Figures through . The clip level in
all cases are the same as the data in Figure . The sparse
model-spaces produce residual panels less like the original data than
the *l*_{2} norm inversion. This results in data residuals often
indistinguishable from the original data to the eye for the sparse
schemes.

Figure 7 Data-space residuals of
shot-gather 08 (Panel (a) from Figure ). Panel (a) shows
the BC, Panel (b) the Cauchy, Panel (c) the *l*_{1}, and Panel (d)
the *l*_{2} inversion results.
