second try! Hi All, To avoid any problems, note that the X-ray program that was said to be on our WWW site, is really at the RadSafe Archive, maintained at UIUC. Thanks for the plug though! We do have a link to it, which you are all welcome to use. Our URL is http://www.umich.edu/~bbusby/ or http://www.sph.umich.edu/~bbusby/
