T-11 Severity
The conference call was held as a continuation of the T-11 severity discussion of 4/23/2010. LZ successfully completed and passed, though on the mild end. Mark Cooper distributed a plot of a candidate re-run to show a change in severity (attached). The difference wasn't as large as originally feared. Much discussion followed. Jim Rutherford was asked to investigate possibilites such as a using correction factors, and/or switching the vis/soot axes. The next call will be Wednesday, May 5th at 11:30 am EDT. Tentative face-to-face meeting dates were set for TUE/WED May 25-26.
