The ZF spectra measured at each temperature can be found in the 'data' subdirectory. The temperature is included in the filename and the data is in the format
time (microseconds), asymmetry (%), error (%)

The corresponding fits can be found in the 'fits' subdirectory. These have the format
time (microseconds), asymmetry (%)

The values of the fit parameters obtained at each temperature can be found in params.dat. This file has the format
Temperature (K), frequency (MHz), frequency error (MHz), lambda_1 (us^{-1}), lambda_1 error (us^{-1}), lambda_2 (us^{-1}), lambda_2 error (us^{-1})

The fit to the temperature dependence of the muon precession frequency shown in Fig.5(e) can be found freq.fit
The first column contains the temperatue in Kelvin and the second column the frequency in MHz.
