Caption: Figure 11.

Contours of constant efficiency (relative to the detector axis) are shown as a function of angle from the detector axis for photons of 15 keV (left panel) and 50 keV (right panel). The axes are marked in arcminutes. The red contour encloses the region where count rate is more than half of the peak value and gives the FWHM of the field of view. The black contours are at intervals of 10%, while the blue contours are at levels of 5%, 1%, 0.1%, and 0.01%.
