spectrum

The spectrum of an optically thin plasma, from the CHIANTI atomic database.

Functions

contribution_function(ion, density, ...[, ...])	Compute the contribution function of every line of an ion.
ions([wavelength_min, wavelength_max, ...])	Find the ions worth computing over a range of wavelengths.
lines(temperature, density, emission_measure)	Compute the emission lines of an optically thin plasma, brightest first.
spectroscopic(ion[, latex])	Write the name of an ion the way a spectroscopist writes it.
stem(spectrum[, ax, num_label, latex, ...])	Draw a spectrum as a stem from zero for each line, and label the brightest of them with the ion which emitted them.
