   We propose spectra for five X-ray clusters with cooling flows. All have
   optical emission lines and blue stars. We will derive the amount of
   cooling material, and the density structure of inhomogeneities. By
   comparison to the optical observations, we will constrain the physical
   state and ultimate repository of the cooling gas. We will measure or
   limit the excess X-ray absorption towards the cooling flows. Previous
   observations suggest that cooling flows occur in clusters which have
   not undergone a recent merger. We will determine the global
   temperature, the temperature profile, and a crude temperature map, and
   compare to ROSAT images to look for merger signatures. If they are
   relaxed clusters, we will use hydrostatic equilibrium to determine the
   amount and distribution of dark matter.
