... eident (eident-1.6) [xmmsas_20050815_1803-6.5.0] . ... At the moment offsets are determined using a grid of offset values, but the accuracy can be much better than the grid size. However, in future we may replace the grid search by a more advanced maximization algorithm. At the moment no role angle optimization is performed. ... The other reason is that to include role angle optimzation a more advanced (three dimensional) maximization algorithm is likely to be necessary. ...
