In most of the literature I have seen the distribution of the surface errors are defined as some sort of bi-variant distribution using 2 angles to describe the deviation of the reflected ray. \r\n\r\nSo I am wondering which of the two distributions offered (normal, and pillbox) tend to correspond best with experimental results and how the distributions are defined, (i.e. what does the value given to m_sigmaSlope equate to in terms of how the distribution is defined). \r\n\r\nThanks in advance for your help.\r\n\r\nRegards,\r\nDaniel\r\n\r\n"}}
