The plasma model is an important tool for astronomers to analyze the observation data of high-energy celestial bodies.The development of accurate and convenient plasma models is helpful for researchers to carry out high-energy X-ray spectroscopic analysis work efficiently.Based on the existing plasma model SASAL,a new high-energy X-ray spectroscopy toolkit SasalPy based on the Python language is further developed.The reliability and accuracy of SasalPy are explained from the aspects of theoretical framework,functionality,and differences.Calculation results of line and continuum radiation show that atomic parameters such as transition rates and collision strengths will significantly impact the synthetic spectrum.Based on the volume differential e-mission measure of the Capella corona,the application of three-temperature spectral synthesis was carried out.The comparison with the radiation loss results of other plasma models showed that SasalPy is more accurate and reliable in the X-ray energy range.
