Figure 6
Rerunning calibration with addition of the precessing ( rot1, rot2) rotation centre parameter and with rotation-affected poni and rot parameters. Note that the output does still show a cyclic behaviour, but not for distance, in contrast to the Fig. 5[link] output, but rather between poni1 and poni2 (as the beam centre precess about the rotation centre), with distance essentially constant, as anticipated. Notice also that both pairs – poni1 and poni2, and rot1 and rot2 – differ in phase by 90°.
