Our main focus is to complete the suite of Spitzer data on debris disks that have been resolved in scattered light. The images of these disks provide information on their structures that can be used to constrain models of their spectral energy distributions. However, there are no MIPS SED mode observations for at least half of the systems resolved in scattered light. By obtaining such observations and combining them with existing IRS low resolution spectra, we will obtain well-sampled SEDs for our modeling. The result should be a suite of much better constrained and hence more realistic models than exist for most debris systems. These models can also be used to learn more about the strengths and weaknesses of models based on SEDs alone, without resolved images. These models will be further refined when after the launch of Herschel with SPIRE low resolution spectra. The MIPS data are essential to avoid a gap from 35 to 200 microns in the well samples regions of the SEDs of these important debris systems. In addition, we will fill in significant omissions in the data for a few debris disks, and will repeat data where there are important discrepancies. This program will therefore take a step toward leaving a solid legacy from Spitzer to debris disk observations with Herschel/SPIRE and JWST/MIRI.
