Chandra near apogee, on descending leg.

Continue OBSID 02222, RXJ 1347.5-1145 2001:130:17:00, ACIS-S HETG. 
SPECTRAL-SPATIAL DIAGNOSTICS OF THE MOST LUMINOUS X-RAY CLUSTER
OF GALAXIES WITH THE HETG - this is a compact high redshift (0.451)
X-ray cluster. Measure its cooling flow and detect a number of
emission lines. Determine the dynamics of X-ray gas early in the
history of cluster formation.
