【 摘 要 】

We present a multi-spectrum fitting software that enables advanced analysis of high-resolution atomic and molecular spectra in a large range of pressures. Individual lines are modeled with theoretical profiles that take into account the non-Voigt line shape effects, such as the speed-dependence of collisional broadening and shift, velocity-changing collisions and their correlations with phase/state changing collisions, first order line mixing and collision-time asymmetry.
