Recently the xy-scanner position for AG camera was compared to those measured using AG images (i.e. sky):</p> <p> dX = -1.748mm<br/>  dY = -0.963mm<br/>  dT = +0.684171deg<br/>  dS = +1.11458e-04  (i.e., x 1.000111458)</p> <p>(xy scanner -&gt; sky images) Based on this comparison. FF position needs to be renewed.</p> INSTRM-1706
