We consider magnetohydrodynamics models and observations of transverse
oscillations in prominence threads to obtain information on their
physical properties such as the magnetic field strength, the plasma
density, or the length. We further compare between short and long thread
limits in period ratio models and compute the relative plausibility of
alternative mechanisms in explaining the observed damping of transverse
oscillations. Bayesian techniques are used for both analyses. The
results show that the physical parameters of interest can be inferred.
Values of period ratio around 1 are more likely in the long thread limit
while shorter and larger values are more likely in the short thread
limit. The mechanism known as resonant absorption in the Alfvén
continuum is the most plausible damping mechanism.
