As per the below email, which Bob forwarded to me, I have just now rebooted the HRS IOCs (iochal4 and iochal6) and the septum IOC (iocha48), and set the "P0 SET" mode on both arms to PREX_B

Scott Higgins made the change to the conversion constant between P0 and Septum momentum - iocha48 needs to be rebooted for this change to take place
Pam Kjeldsen made the changes for loading different quadrupole constants - iocha14 (left HRS) & iocha16 (right HRS) need to be rebooted for these changes to take place. After rebooting, the "Optics Mode" selection switch (access through blue button next to the "P0 SET" field of each spectrometer) should be set to "PREX_B" (new quad settings). The previous values should still be available as "PREX_T1"
