Abstract:
Lines with no linear polarization induced by Zeeman effect are unaffected
by instrumental polarization. We compile 86 such electric dipole lines with
differing temperature and magnetic field sensitivities. In addition, we list
420 spectral lines which produce negligible linear polarization. In most
cases, this second set can also be regarded as lines unaffected by
instrumental polarization.
