   ASCA observations of M87 have two major objectives. One is the study
   of the ~10solar mass per year cooling flow near the center of the
   galaxy. Extensive spectral studies with Enstein imagers and
   spectrometers show clear evidenceof gas covering nearly a decade in
   temperature. ASCA's combined spatial andspectral response will permit
   a detailed model of the cooling flow andcould show clear evidence for
   mass dropping out at large radii. The secondobjective is to make an
   improved measurement of the radial profile of the large binding mass
   in M87. This requires a good temperature measurment out to large
   radii. We propose two different pointings and will also make use of
   the separate M84/M86 observation to give three overlapping GIS fields.
