line_1: This proposal will test the new commanding capability
line_2: of using more than just the two central target acquisition
line_3: diodes during the locate phase of a target acquisition.
line_4: An extended object will be acquired and the fine
line_5: x-balancing will be done with 2, 4, 6, and 8 diodes to
line_6: test all possible modes of this new capability.

question: 2
section: 1
line_1: The goal of this test is to exercise the new commanding
line_2: capability that permits a better fine x-centering
line_3: during the locate phase of a target acquistion (or
line_4: during an ACQ/PEAKUP.) The locate phase first centers
line_5: the object in y: first coarse, then fine. The locate phase
line_6: next centers in x; again in two steps: coarse and fine.
line_7: During the coarse balance the GHRS attempts to position the
line_8: object such that the 4th target acquistion diode is recording
line_9: the greatest flux (there are 8 target acquisition diodes.)
line_10: Previously, the second step was to use two deflection steps
line_11: to move the object toward diode 5--stopping when diode 5
line_12: recorded the greatest flux. The object was then effectively
line_13: centered when the flux was balanced between diodes 4 and 5.
line_14: With the new commanding we now have the ability to specify
line_15: using diode 4 vs. diode 5 or the sum of diodes 3 and 4
line_16: vs. the sum of diodes 5 and 6 or the sum of diodes 2 and
line_17: 3 and 4 vs., etc. during the fine centering.
line_18: This should improve our ability to properly center extended
line_19: objects.
