Figure 8
Symbols: measured vertical FWHM of the central peak as a function of calibrated slit width, at 12.0 and 22.1 keV, for slits A and B. Curves: calculated FWHM, for best-fit incident divergences given in Table 2, using actual slit and source positions. Dashed lines: diffraction limits for perfect resolution for each wavelength. Dash-dot lines: slit width contributions to resolution for each slit. |
