<DIV><SPAN class=287055614-19022007><FONT face=Arial size=2>but I don't know how
to interpret it. They must somehow describe how the CSI grid is
oriented... if, for instance, the first 3 of these 5 header lines
describes a position (maybe of the center of the grid), the question is: in
respect to what? to the high definition T1 image on which the CSI slice was
positioned, or to the center of the magnet?</FONT></SPAN></DIV>
