Fits to μAtt, μpairp, and μCompton enable determination of external attenuation, self absorption, and the detector efficieincy.
The continuum is found by fitting single regions with smooth edges and centers found by an error including modification of ..\..\interpolation\Bli.htm. The fitted regions are interpolated with a cubic spline.
Mostly 128hour.dat and 128hourbkg.dat.
A set of files containing the peaks and intensities associated with various nuclear decays.
peakfit
Bumps
in the data are fitted to individual peaks.
This folder contains the details and code to represent individual peaks.
This folder contains the code templfit that fits the nuclide intensities, energy coefficients, width coefficients, efficiency coefficients, self absorption coefficients, and attenuation coefficients to the data.
This folder contains code for energy, attenuation, and width calibration using a set of peaks found by peakfit.
A menu gives display options.
The actual display uses gnuplot(..\..\gplot\Welcome.htm)
A
1995 shareware version of Robfit is
described in srobfit\Srobfit.htm. The graphics
have been updated from dos to windows. Modifications to enable Robfit
to run in unix are
given in srobunix\Welcome.htm.

File Formats for RobFit
RobFit assumes that the data files have
been processed into the RobFit SP ASCII format or the Cambio CML format. This
processing can be done from almost any format with the Cambio program, which can be obtained at https://hekili.ca.sandia.gov/Cambio/.
If saving to the Cambio CML format
is used, Cambio can also be used to perform an initial energy calibration that
will assist in beginning a RobFit
analysis.
Serious
development of Robfit for nuclear
spectral analysis began in 1984. Its main application was the analysis of HPGe data taken during a high-altitude balloon flight over
Antarctica in January, 1988, to analyze gamma rays from the 1987A Supernova to
look for evidence of nucleogenesis of heavy nuclei.
In 1989 official permission to make RobFit code into open source was granted.
