Our system of equations is constituted by collecting relations (4),
(6), (7), (8), and (13):

(14) |

Because the and vectors are two-dimensional,
the first, second, and sixth relations of system (14)
give equations, yielding a set of nine equations.
The unknowns are , , *t*_{s}, *t*_{g}, *t*_{0}, and
. As described in the preamble, the vectors
have only two unknown parameters, *p*_{x} and *p*_{y} (or *p* and ).
Similarly, is a two-dimensional unknown vector. Therefore,
system (14) relates nine unknowns with the known parameters
, *t*_{sg}, , , and the ray tracing
tables , , and .
