ABSTRACT



The binary search target acquisition tests at Lockheed Missiles and
Space Company were run under the new fliqht software, version 3.6. The
final run of the TA tests was cornpletely successful, with the target
pJ.aced on the Y edge of the aperture when it was appropriate, and
with the software bränching when it was appropriate. The correct
po~itions are found to within ±2vi in X and Y for a source with counts
of about 1500. Considering that the dimension of the smallest FOS
aperture (0~1), is 14~ in the image plane, this is a very acceptable
accuracy.
