Sednterp was originally developed as a template for a spreadsheet by Thomas M. Laue, Bhairavi D. Shah, Theresa M. Ridgeway and Sandra L. Pelletier. A previous version of a sedimentation interpretation program is completely described in a Chapter of "Analytical Ultracentrifugation in Biochemistry and Polymer Science" (Ref. 59). This chapter does not describe all of the ideas used in or features found in Sednterp, but it does give the theoretical background useful to understand Sednterp. In a few cases the formulae used in Sednterp differ from those in Ref. 59 (mostly due to correction of typographical errors), and in such cases those differences are noted herein.
The person primarily responsible for the past and future development of Sednterp is Dr. Thomas Laue, Department of Biochemistry, University of New Hampshire, Durham, New Hampshire 03824. Telephone 603-862-2459, FAX 603-862-4013.
