We use the CXC CIAO software to fit models of the spatial structure of the X-ray jet emitted from the quasar PKS0637-752. After careful assessment of scattering from the central source, and establishing a limit to any X-ray emission from the cluster, we detect X-ray emission from the eastern radio knot and past the bend of the radio jet to the northwest. We attempt to fit the bright western jet as either a series of point sources only, or as points at the 4 brightest knots with a spatially continous cylinder from 4 to 11 arcsec west of the nucleus. The fits lead to a wide range of intrinsic parameters, depending on whether the jet is non-relativistic and in the plane of the sky, or is relativistic and pointing within 6 degrees of our line of sight as shown by VLBI monitoring for the pc scale jet in the quasar nucleus.

This research has been sponsored by the ISAS/VSOP project, CSIRO, and several NASA contracts and grants including NAS8-39073 to the Chandra X-ray Center.
