Finish obsid 9809, an ACIS-S observation of 4C 74.26, to study the offset between the terminal X-ray and radio hotspots. Then do obsid 9765, an HRC-S/LETG observation of the Crab Nebula and Pulsar, using the HRC shutter to help attenuate rates with an objective, among others, to measure the surface temperature of the neutron star.
