This screen shows the mount alignment parameters that the current model has.<br />

3-5 alignments calculate MA, ME additionally.<br />
<br />
6th..9th alignment add CH and NP non-perpendicularity parameters to the
model.<br />
<br />
From 10th alignment up counterweight flexure DAF is added. <br />
<br />
All Values are in arc-seconds.</span></td>
