LFPF is software for estimating the position, width and asymmetry of the interface between dissimilar materials
LFPF is written by William H. Kirchhoff. The Logistic Function Profile Fitting program is based on a Fortran program written for DOS and originally issued under the name LOGIT. This program was successfully used to fit Auger sputter-depth-profile data [W. H. Kirchhoff, G. P. Chambers, and J. Fine, J. Vac. Sci. Tech. A 4, 1666 (1986)]. This approach and the associated software were applied in a number of laboratories, and formed the basis for an ASTM standard [E 1636-04: Standard Practice for Analytically Describing Sputter-Depth-Profile Data by an Extended Logistic Function]. The logistic function (although not the specific LOGIT or LFPF software) has also been used to describe Auger linescans [S. A. Wight and C. J. Powell, J. Vac. Sci. Tech. A 24, 1024 (2006)].
DTSA II is a multiplatform software package for quantitative x-ray microanalysis
DTSA-II is a multiplatform software package for quantitative x-ray microanalysis. DTSA-II was inspired by the popular Desktop Spectrum Analyzer (DTSA) package developed by Chuck Fiori, Carol Swyt-Thomas, and Bob Myklebust at NIST and NIH in the '80's and early '90's.
NISTMonte is a platform for modeling electron and x-ray transport
NISTMonte is a full-featured Monte Carlo simulation of electron and x-ray transport in complex 3D sample geometries. NISTMonte provides a flexible script-based interface which permits complex multi-material sample geometries and multiple detection schemes including spectrum generation. NISTMonte is written in Java and can run on Windows, Linux, Solaris, Apple OSX and any other Java 5 supported platform. Source code is provided.
Lispix is an image analysis program for the Windows and Macintosh platforms.
Lispix, and its predecessor are freeware image analysis packages written in Lisp by Dave Bright at NIST. Features of Lispix include RGB color overlays, real image arithmetic, two dimensional histograms, averaged scan lines, data cubes, image registration, stereo movies, linear Hough transform, FFT, simultaneous zoom and scroll with navigator, measurements and statistics on groups of images.
