Do obsid 6174, an ACIS-S/HETG GTO observation of the underluminous supermassive black hole in M81*, to test theoretical models of low-efficiency accretion and outflow. Then obsid 5449, and ACIS-S observation of the low luminosity of the quiescent neutron star binary 1H 1905+000. No Comm this shift.
