   RCW 86 has an unusual spectrum with a soft thermal component and a
   high temperature tail with iron line emission. The surfacebrightness
   is simple with a bent bright arc. This remnant is in theadiabatic
   phase, probably, and will be useful for non equilibriumionization
   modelling. For PV phase calibration, spatial and spectralfitting
   routines can be tested.
