AI Technical Summary
Existing techniques for fitting high-energy particle energy spectra have problems such as requiring prior assumptions about the energy spectrum shape, being unable to fit triple-fold power-law spectra, and not considering energy errors, resulting in inaccurate fitting results.
An energy spectrum fitting equation is constructed, taking into account flux and energy error. The tanh function is used to describe the smooth transition within the energy range. The parameters are optimized by chi-square statistics and gradient information to achieve self-consistent fitting of the three-fold power-law spectrum.
It can self-consistently fit various energy spectrum shapes, including trifold power-law spectra, and provide more accurate information on energy particle distribution, especially transition energies and width information.
