7. Tools

The website provides serveral powerful online tools to analyze and compare spectra.

General

Here the model parameters can be specified, including wavelength (or wavenumber) range, line profile to use, and which--if any-- emission model to apply.

Co-add

This tool co-adds the spectra of the selected species.

Stack

This tool vertically stacks the spectra of the selected species, facilitating direct comparision.

Spectral fit

This tool fits a user-supplied spectrum with the spectra of the selected species. Currently, two-column ASCII (wavelength, flux), VOTABLE, and ISO/Spitzer-YAAR are supported.

Temperature stack

This tool vertically stacks the spectrum of the selected species for a given set of excitation temperatures, facilitating direct comparision.
