Table 4.

A comparison of the NRMS versus iteration for different factored models.

Iteration number	50	150	200
${\mathit{G}}_{\text{solid}.\text{ang}}+{\mathit{B}}_{\text{solid}.\text{ang}}^{2\text{D}}$	1.5%	2.6%	4.4%
${\mathit{G}}_{\text{line}.int}+{\mathit{B}}_{\text{line}.int}^{2\text{D}}+{\mathit{R}}_{\text{line}.int}^{\text{tr}}+{\mathit{R}}_{\text{line}.int}^{\text{a}}$	1.4%	3.1%	4.1%
