MuFiS stands for "Multipurpose Fireball Software". This software has been developed during the years 2017-2020 for the physical analysis of the bolides observed in the Earth's atmosphere within the PRISMA Project (http://www.prisma.inaf.it/). It is a software that runs under 64-bit Windows inside a DOS or PowerShell window, developed and compiled with Matlab R2015b. There are two modes of use:
1-BASIC mode is the default. It is possible to obtain the complete triangulation of the trajectory (altitude and velocity as a function of time, absolute and apparent magnitude as a function of time, coordinates of the apparent radiant, etc.), a first reconstruction of the heliocentric orbit with uncertainty estimate made using Monte Carlo and, if the final kinematic velocity is below of 6 km/s, a kinematic model of the dark flight with relative estimate of the point of fall to the ground of any residual meteoroid. As a kinematic model for velocity as a function of altitude Ceplecha model is used.
2-In the ADVANCED mode MuFiS always performs the triangulation as in the BASIC mode, but this is followed by the dynamic analysis of the motion of the bolide in the atmosphere to obtain speed to infinity, m/S ratio (from which, assuming an average density of 3500 kg/cm^3, mass and dimensions are found separately), ablation coefficient and velocity at the initial point.
