      Description

      The convergence quality during the September 2021 run was not as good as what had been determined previously at ASRD. Please find the cause.

      This could be due to:

      1. The expected cobra centers provided did not match the measured centers.
      2. Some fiducial fibers were not correctly identified.

      Quoting a comment by rhl in his email 2021-10-07:

      I think that we didn't propagate the relevant opdb tables to provide the target (x, y) (mm) and (theta, phi) (radians), so there's a
      prerequisite (load the opdb back to the beginning of the September run), and a task (load the opdb tables) before we next run the system.
