Fig. 5: Estimated motor force f0 and fraction of attached motors r from the experimental data.

Best fit parameters from the experimental data sets of rabbit soleus HMMs (red symbols) and rabbit psoas HMMs (blue symbols). Mean values and standard deviations are obtained by averaging over 20 independent realisations of the stochastic fitting procedure for each data record (coloured small dots). Different tones refer to different experiments. Each solid line represents the hyperbola on which each of the pair (f0, r) is constrained to be, according to the mean field analysis.
