Deconvolution of 3D-fission track length histograms

The codes correct histograms of confined horizontal fission track lengths and calculates the age distribution. The code is for tracks measurement of the track angles to the c-axis. Equations relating 3D track length histograms and associated surface track densities to track ages are given in a submission to Geochronology July 2021. An early version of equations are given in Jensen et al. (1992) and illustrated in a poster (Jensen and Hansen, 2018). Inversion is based on probabilistic theory (Tarantola, 2005). The code can be used to separate the pre- and post-depositional parts of corrected fission track length histograms. A code for track measurements without the angle to the c-axis is uploaded separately. Programs are running in GNU Octave
