Figure 3
Angular profiles of DW100 emission at 30 keV (solid line), 50 keV (dashed line) and 70 keV (dotted line) in the horizontal (a) and the vertical (b) directions, respectively. The vertical dash-dotted lines show the angular acceptance of the fixed mask, which defines a 1.1 mrad aperture horizontally and a 0.1 mrad aperture vertically. |
