All studies will take data at 100% torus field (negatives inbending) and 100% solenoid field (positive polarity on supply). The beam position should be as indicated above. Make sure FSD thresholds are set correctly for whatever current is selected (refer to instructions in the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf]), integration time is set to 5 ms, and that the orbit locks are on.

<!--* If beam profiles at the tagger are acceptable, move to beam tuning to the Faraday Cup. Again, refer to the instructions in the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf]. Compare harp scan with the one from 1/25 swing shift (https://logbooks.jlab.org/entry/3520947).  -->
