The Center function determines via software the center of the fiducial. The parameters for the

function, the edges of the fiducial structure, are selected via a dialog. The system draws edge line

markings as suggestions at possible edge positions. 6

Å With the arrow keys shift the current edge line marking designated in the header.

Å With Return you can accept the position of the suggested edge line marking or the one whose

position you changed. The system will then show you the next edge line marking. The se-

quence in which testing takes place is ’Fiducial edge left’, ’Fiducial edge right’, ’Fiducial edge

top’, and lastly, ’Fiducial edge bottom’. This notation appears in the header.
