Shutter Focus

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.
