Use this form to run the STSDAS task nebular.ionic.
This task can calculate the level populations, critical densities, and line
emissivities for a selected ion, given the electron temperature and density.
If the flux and wavelength of a particular emission line are also given, this
task will calculate the ionic abundance, relative to H+.
Simply fill in the appropriate information below and press the
|Perform Calculation| button to calculate the line
Detailed help is
available in the STSDAS on-line documentation, but bear in mind that the
interface for this form is different.
