Transitions of astrophysical interest close
to the UV atmospheric cut-off
Marcos Diaz - Oct./97
Below I list the most important emission lines (forbidden and permitted) in the range from 330 to 400 nm. They can be used as an additional guide for UV spectral coverage and efficiency trades. Lists are not intended to be 100% complete; it is a compilation from a few personal notes and line lists. AGN lines may be, of course, redshifted to longer wavelengths.
