Barry -- You might be interested in the following document, written by Brett Nordgren (he used to regularly post to this list). It is an analysis of Sean-Thomas' equations describing the VBB, and takes them apart term by term. http://members.home.net/nordgren/public/loop3.pdf I found it an invaluable aid toward understanding the equations involved. -- Karl _____________________________________________________________________ Public Seismic Network Mailing List (PSN-L)
