2. 2 Primary Purpose of Today's Workshop  The purpose of convening everyone to review the preliminary results and observations is:  To ensure that we correctly interpret the various methods.  To obtain feedback and insights from contributors.  Our approach to interpreting the results  Our specific observations  Other things that we may need to think about or address  To begin the process of coming to a collective consensus. The product of this study will be more useful to the ground motion community if we can all establish group agreement on the results.  Note: Our dialogue will be ongoing, but this is our only formal meeting before the preparation of the first PEER report.
