Abstract:
Some points concerning the characteristics of the X-ray simulation code SHADOW [Welnak et al. (1994). Nucl. Instrum. Methods, A347, 344-347] are clarified which are not correctly mentioned by Yamada et al. [J. Synchrotron Rad. (2001), 8, 1047-1050]. It is shown that, contrary to the Authors' statement, some functionality of their new program is not original. In particular, we show that SHADOW can deal correctly with crystal monochromators.
