Hi Tony, I agree that Figure 1.13 has the radians conversion missing. I generated the same plot in Excel (both with and without the Pi/180 factor) to confirm your observation. As you pointed out correctly, in calculations, delta theta should be in radians. It's a common mistake that I observe with

Dear Rietvelders, I might not be the first to ask this question, but I found the Figure 1.13 of book "Powder Diffraction - Theory and Practice" is problematic. The equation 40 on the previous page is correct. But the authors seems wrongly treated "Δθ" as angle not radian w
