Publisher description for BinomFit

BinomFit program icon

BinomFit provides tools for analysis and interpretation of fission-track grain-age data. Key Features:- Estimation of ages and uncertainties for individual grains and for concordant and mixed grain age distributions. The estimates are based on an exact binomial algorithm (Sneyd, 1984) that can account for grains with any number of tracks, including zero track grains. This approach is essential for estimating ages for young fission-track samples.- Estimation of components or peaks in a mixed fission-track grain-age distribution using the binomial peak-fitting algorithm of Galbraith and Green (1990) and Galbraith and Laslett (1993). The program supports both automatic and manual modes for searching and identifying the optimal number of significant peaks. The program can handle up to 1000 grain ages and solve for as many as 10 peaks.- Graphical presentation of results using the probability density plot, the radial plot, and the P(F) plot.- Generation of output files that can be used to construct these plots in other software, such as Excel or SigmaPlot.- Option to send all results to a user-selected printer, including plots and detailed grain-age data. Printed output includes standard statistics, such as pool and central ages, plus accurate estimates of confidence intervals for grain ages, including grains with low track counts.- Datasets can be edited to understand the influence of anomalous grains on the peak-fit solution.System Requirements:The program runs under the Windows operating system (Windows 95 or newer).
