By mouse clicks and slider operations, you generate starting values for a curve that approximates experimental data by overlaying a number of Gaussians. The fit can then be carried out by a standard Levenberg-Marquardt procedure. The residuals of the fit can be analyzed for standard distribution. Any parameter of the fit can be treated as a constant by a simple click into the spread sheet like table of results. Standard deviations are computed for every parameter.

Interactive Mesh Design and Filled Contours TriFills is a Java Applet that is loaded across the network into your browser. You design a triangle mesh and assign values to each node of the mesh. Then you can display linear contours, optionally filled with colored areas, or interpolate within the triangles. References to part of the Java source code are given. The triangle mesh can either be generated, or a list of triangles can be passed to the procedure.
