 Purpose:  We have installed for the first half of the night a stripped down, revised version of the pointing code.   We wish to determine what residuals remain as a function of Az.    We want observations near the center of the track (being exactly at the center is NOT required).    We want the observations to be "normal" so if you have to redo a trajectory (due to a fault or human error) please move the Az off and then re-acquire the field.

+Procedure:
+*  Select a star a little after the start of the track but bright enough to recognize the field run through shuffle for the IHMP position.
+*  Send the star to TCS and go next
+*  After the correct for structure has completed the TO should focus based on ACAM image quality; do a GROC if needed.
+*  Save an ACAM image
+*  Look at both the fake ACAM and real ACAM and determine the position for the target star on the real ACAM.
