Paper Abstract
We present an overview update of the metrologic approach to be employed for the segmented mirror fabrication for the
IXO soft x-ray telescope. We compare results achieved to date with mission requirements. This is discussed in terms of
inherent capability versus in-practice capability. We find that all the needed metrology equipment are in hand but that a
number of the needed quantities remain too uncertain relative to mission requirements. This is driven by the mounting
of the mirrors themselves. We then discuss some plans for addressing the mirror mounting issues. Finally, we also
briefly discuss some promising mandrel metrology techniques.
