** Previous:** Diagonal weighting preconditioning

This is equivalent to pre-multiplying the matrix **L** and the data
vector by a diagonal matrix and solving the system:

| |
(55) |

where the sums of the elements from each row of **L** are along the diagonal
of .
Since each row corresponds to a summation surface (impulse
response of ), then is normalization by the
coverage before AMO.
