To complete the final estimation of , we make a simple
set of mappings from the least-squares (or *l _{1}*) estimates derived
in the previous sections.
A map of can be obtained directly from the result of
(102) or (103):

(104) |

Then, since there is a one-to-one mapping of to any point , and to the same point , there is a unique map of and to such that:

(105) |

which is the desired result. This completes the angle-dependent reflectivity estimation process.
