The purpose of this ticket is to quantify how much FRD can vary to hysteresis in fiber positioning, and more specifically, how much out-of-focus calibration is required for FRD extraction.</p> <p>Some of this work may require data from the instrument, but consideration into how much hysteresis could be tolerated can be considered now.</p> PIPE2D-629

Better understand the hysteresis in the FRD with Cobra motion

While this work would be worthwhile, it is not in the current scope of Brent's activity during this timeframe and thus put on hold.</p> Relates PIPE2D-630 PIPE2D-628 PIPE2D-627 Development Rank 0|02qpq3:r0v
