Previous: 4.4.1 Introduction
Shutter Focus tests are designed to find rapidly the focal spot of the
HRMA and to develop estimates of where to move the ACIS or ACIS-2C by
FAM motions to find the prime focal spot and place it at the desired
pixel location. This test is iterated, changing X until the minimum
diameter 10% power level is found. Note: due to gravitational
distortion effects on telescope blur it is expected that the blur will
be deformed in Y and Z. The actual criterion will be minimum image
width in the Y (grating dispersion) direction.
