JOFILUREN: A wavelet code for data analysis and de-noising
Other - Software code, 2025

Wavelets are a powerful mathematical tool whose most celebrated applications are the analysis, compression and de-noising of scientific data.  JOFILUREN is a wavelet code designed for data analysis and de-noising applications.  It is written in Fortran, is portable, and can also be used for studying and reducing the physical effects of particle noise in particle-mesh computer simulations.  JOFILUREN was introduced in Paper I, was described in Paper II, was also used in Paper III (see references below), and is published in the Astrophysics Source Code Library (see ASCL Code Record ascl:2504.034).
