The CHIANTI database consists of 4 primary ASCII files for each ion in the database. contains the energy levels in cm^(-1) It includes both experimental data and theoretical values of the levels energies. ... Wavelengths are based on experimental level energies where available; wavelengths calculated from theoretical energies are less accurate and are given as negative values. ... contains the spline fits to the electron collision strengths scaled according to Burgess and Tully (1992). ...

... were entered in the atlas. ... In so doing lines were selected which yielded radial velocities close to the symbiotic velocity of MWC 560 (+35 km/s). ... The visible spectrum of MWC 560 is poor in absorption lines especially near the brightness maximum. In our atlas are visible only the blue-shifted components of , , NaI and FeII(42), interstellar lines NaI, a few diffuse interstellar bands (DIB) and telluric lines of and and, at length, traces of the spectra of the M giant. ...
