      Description

      The task is to analyze and find how much defocus is needed in order to measure the realistic change of frd, in realistic conditions. This is to be done with our current knowledge about the system and with the 2d psf modeling code. 

      The task includes (we might break this into finer additional tickets):

      1. determining what values of frd change we expect and what level do we need to measure (we might need to solicit some input from Jim on this)
      2. Determine defocus values that allow to measure these changes as a function of signal-noise and position on the detector (center, edges...)

      This is rehashing of PIPE2D-452 updated to signify updated constraints and the transfer of this work to Caltech
