Annotation	The Fortran computer program performs inversion of amplitude ratios of P, SH and SV seismic waves together with polarities of P waves into the mechanism of the seismic source in the description of unconstrained moment tensor (MT). As such, it allows describe general dipole sources including isotropic components: e.g., it is suitable to retrieve the parameters of both a shear dislocation common at foci of tectonic earthquakes (described as a double-couple, DC) and volumetric sources as tensile cracks or cavity implosions. Additional benefit of processing of amplitude ratios instead of absolute amplitudes is lifting the demand for a precise calibration of the instrument.
