Table 1: Atomic parameters and height of formation of the Fe II lines selected for observations of shock signatures. $E_{\rm p}$ and $W_{\lambda }$ stand for the excitation potential of the lower level and the equivalent width of the line, respectively. The Landé factors are given for the cases of LS coupling and the empirical values. The height of formation was calculated according to the MACKKL model of the solar photosphere (Maltby et al. (1986) by Gadun (2000). References: 1 - Allende Prieto & Garciá López (1998); 2 - Moore (1972); 3 - Kurucz (1990); 4 - Solanki & Stenflo (1985); 5 - Moore et al. (1966).
