The CHIANTI atomic database contains atomic energy levels, wavelengths, radiative transition probabilities, and collisional excitation data for a large number of ions of astrophysical interest. CHIANTI also includes a suite of IDL routines to calculate synthetic spectra and carry out plasma diagnostics. Version 5 has been released, which includes severalnewfeatures,aswellasnewdataformanyions.ThenewfeaturesinCHIANTIareasfollows:theinclusionof ionization and recombination rates to individual excited levels as a means to populate atomic levels; data for Kand Kemission from Fe ii to Fe xxiv; new data for high-energy configurations in Fe xvii to Fe xxiii; and a complete reassessment of level energies and line identifications in the X-ray range, multitemperature particle distributions, and photoexcitationfromanyuser-definedradiationfield.Newdataforionsalreadyinthedatabase,aswellasdataforions notpresentinearlierversionsofthedatabase,arealsoincluded.Version5ofCHIANTIrepresentsamajorimprove- ment in the calculation ofline emissivities and syntheticspectra in the X-ray range and expands and improves theo- retical spectra calculations in all other wavelength ranges.
