5.1 Knife-Edge Focus

Locate focal position along optical axis such that image shift in knife-edge test is < 0.1" . 5 positions along x-axis. hsiimage with 4 shutter settings at each focal setting. Unresolved issue: how will we coordinate between the XDACS and the HRC to control the acquisition of data and the control of the shutters? What GSE will be used to make the SIM motions?

maximize sensitivity for point source detection, for example, knots in jets^c.

5.3 Effective Area Confirmation

Effective area at one image radius

Accuracy to 1%. The HRC must be translated & rotated so the images striking it duplicate the conditions in flight. The SIM rotates and translates to keep the HRC detectors in a rigid body relationship with the HRMA. XGA turned down to 10-4 of max.
