Table 1:   Table of the most polarizing atomic spectral lines of the second solar spectrum (3160 Å-6995 Å). The lines are listed by increasing wavelength. The various quantities that are listed for each line are described in Sect. 2.3.

Table 2:   Spectroscopic properties of the atomic spectral lines listed in Table 1, which present unambiguous identification and Q/I profile classification and measurement. The lines are collected element by element. The various quantities that are listed for each line are described in Sect. 3.
