We took more pointing data later on during the night of 20100720, but this time in a more careful manner. We performed large moves back to Az = 0 several times during the course of taking the previous data which we think probably created the large amount of scatter. This data was taken by making small 10 degree moves in Azimuth in the same direction between each observation. We took one set moving in a clockwise direction from Az=0 and another set moving counter-clockwise from Az=360. As we hoped, taking data in this way shows the systematic cyclical signature much more clearly. Recall that for our experiment the elevation is fixed by leaving the tracker locked at (0,0) and thus should remain constant.
