Results of simulation tests.

Spectra of Doppler broadened pionic hydrogen have been simulated and fitted for the \( \pi H_{2\rightarrow 1} \) and the \( \pi H_{3\rightarrow 1} \) transitions. The velocity profile of Figures 3 and 4 have been used for the simulation. The resolution function was taken to be gaussian with a FWHM of 221 meV and 262 meV, respectively. The Lorentzian width was assumed to be 950 meV. The peak/background ratio was assumed to be about 100:1 and the intensity in the transition was varied between 5000 and 40000 entries in the measured transition.
