General
  • These settings are common to most tools.
  • Select transitions between and
  • Convolve transitions with a line profile having a full-width-at-half-maximum (FWHM) of cm-1
  • Apply * emission model at K
    *The emission models make use of empirical approximations.
Co-add
  • This tool will co-add the spectra in the provided frequency range of the species you selected with selected weights. With the given emission model, the bands are convolved with the chosen emission profile with chosen width. This is then the (weighted) emission spectrum from the selected mixture of PAHs. Due to resource constraints this tool is limited to 256 species.
  • Choose a weighting scheme:

    Up to 5 weights can be set manually.

Stack
  • This tool will stack the spectra in the provided frequency range of up-to ten species you selected. With the given emission model, the bands are convolved with the chosen emission profile with chosen width. This then allows for the direct comparison of the individual emission spectra of the first ten PAHs selected. Due to resource constraints this tool is limited to 10 species.
Temperature stack
  • This tool will stack the spectrum in the provided frequency range of one of the species you selected at one-to-five different temperatures. Which species can be chosen below. The bands are convolved with the chosen emission profile with chosen width. This then allows for the direct comparison of the spectrum from one of the PAHs selected at different emission temperatures.
  • Choose a PAH from your current selection:
  • Choose up to 5 different blackbody temperatures (in Kelvin)
