For these planetary nebula spectra, Castelli/Kurucz or Rauch models were used as inputs to the CLOUDY nebular simulations, see https://www.nublado.org/wiki/StellarAtmospheres where the use of these models in CLOUDY is described. The templates were generated for Kurucz/Atlas or Rauch stellar atmosphere models with a constant density nebula. Spectra were then simulated and rebinned to a uniform resolution of 6000. Each of the generated spectra has different luminosities and different Hydrogen densities. The abundances were scaled solar, except for the 53000 K carbon-rich model, which was matched to the data for the specific source SMP LMC 58. The spectra have either silicate or amorphous carbon dust in the gas, and are for an assumed distance of 1 kpc. The lines in the spectra have a constant 50 km/s velocity width, and the line profiles were calculated at 10 times oversampling. The wavelengths are in Angstroms, while the fluxes are in erg/s/cm^2/Angstrom.
