The analysis of quickly damped transverse oscillations of solar coronal loopsusing magneto-hydrodynamic seismology allow us to infer physical parametersthat are difficult to measure otherwise. Under the assumption that such dampedoscillations are due to the resonant conversion of global modes into Alfvenoscillations of the tube surface, we carry out a global seismological analysisof a large set of coronal loops. A Bayesian hierarchical method is used toobtain distributions for coronal loop physical parameters by means of a globalanalysis of a large number of observations. The resulting distributionssummarise global information and constitute data-favoured information that canbe used for the inversion of individual events. The results strongly suggestthat internal Alfven travel times along the loop are larger than 100 s andsmaller than 540 s with 95% probability. Likewise, the density contrast betweenthe loop interior and the surrounding is larger than 2.3 and below 6.9 with 95%probability.
