Updated version of KAPPA package for the calculation of optically thin spectra for the non-Maxwellian kappa-distributions

Kappa-distributions are non-thermal distributions with a Maxwellian core and a high-energy tail. Their presence in the solar corona and transition region follows from many theoretical calculations and spectroscopic diagnostic of solar plasma. This diagnostic is based on the changes in line intensities with the non-Maxwellian distributions though the changes of individual ionization, recombination and collisional excitation rates. The calculation of synthetic spectra for the kappa-distributions can be performed using software and database KAPPA package. The package is based on the freely available CHIANTI database and software (Dzifcakova et al. 2015, ApJ 217, 14). New version of KAPPA package corresponds to the latest CHIANTI 9 database. The package contains ionization and recombination rates with the ionization equilibria together with excitation rates for a wide range of kappa. KAPPA allows us to calculate effects of distribution not only on the intensities of the allowed and forbidden lines but also on the intensities of the dielectronic satellite lines and continuum emission. This enables us to propose the diagnostics of plasma parameters and distribution, to calculate the effect of the kappa-distributions on the EUV and X-ray filter responses, to study the influence of the kappa-distribution on diagnosed temperature and DEM, and so on.
