Targeting accuracy for DESI fiber robots over a 2.5 week period of survey operations, during which the Focal Plane System acquired more than 1.2 million targets. During this period, we operated with code that corrects some of the dome turbulence effects in the FVC measurement. This reduced the positioning error to 6 μm rms (prior performance was 9 μm rms, as shown in Figure 4).
