Characterize the RMS wavefront across the detector

There were discussions during the PFS meting about focus issues and how to optimize the instrument. There was discussions about the difference between ensquared energy requirement and how does it correlate with wavefront parameters that I am determined from the donut analysis.  My understanding is that Jim wants to see the RMS wavefront error image across the detector and compare that with ensquared energy measured. I will verify this with Jim and than update this ticket.
