James reports: "James analyzed differences between the behavior of 4 parameter interfaces (legacy Ftools interface, PIL, the Ciao interface and the new Ape interface), and met with the HEASARC development team to determine a set of changes to Ape that maximize backward compatibility." Ape will be our new PIL at some point.

He also made further investigations of biases in the measured fluxes of sources. And if you are interested, you will have to look.
