      Description

      From Jim's notes during discussion on Friday (August 29):

      "The notion is that we will have images with high S/N from some standard
      configuration which can be used as a template and for which we have
      PSFs.  When we are on the sky with some different configuration, we need
      to be able to measure the delta `FRD' to predict the PSFs in this
      configuration."

      This combines all of the work that I've done so far into a compact deliverable. In particular, the purpose of this ticket is to deliver code that takes in a base fiber configurations' PSFs and corresponding FRD values as well as the current fiber configurations' PSFs to output FRD values for all of the current fiber configurations.
