$\begin{figure} \par\includegraphics[height=9cm,clip]{8046Fig1.eps}\end{figure}$ Figure 1: Differential Hanle effect in synthetic Stokes profiles of R-branch lines in the CN violet (0,0) band. For selected angular momenta N of the lower state we show the complete doublet, which causes the double peak structure for large N. Three values for the turbulent magnetic field strength were chosen, giving identical Stokes I profiles but large modifications in the Stokes Q profiles: 0 G (upper curve), 10 G (intermediate curve), and 100 G (lower curve). In this and all other figures we assume an elastic collision rate equal to zero.

$\begin{figure} \par\includegraphics[width=9cm,clip]{8046Fig2.eps}\end{figure}$ Figure 2: The dependence of the Hanle depolarization factor $W_{\rm H}$ , given in Eq. (7), on the magnetic field strength and the N quantum number for the CN violet (0,0) band. The three curves correspond to the depolarization factors $W_{\rm H}$ equal to 0.9 (solid), 0.5 (dashed), and 0.3 (dotted), the last of which is already close to the asymptotic saturation limit of 0.2.

The panels show 2-dimensional cuts in the parameter space through the minimum ${\chi }_{\rm min}^2=1.13$ . Numbers on the contours indicate the values of ${\chi }^2$ as defined in Eq. (16).

$\begin{figure} \par\includegraphics[height=8.8cm,clip]{8046Fig4.eps}\end{figure}$ Figure 4: Fits to the observations (thin solid lines) of Stokes $I/I_{\rm c}$ and $Q/I_{\rm c}$ in the first wavelength region ( $3865.9\!\!-\!\!3866.8$ Å). The assumed magnetic field strengths in the calculated spectra are 0 G (no depolarization, thick dashed line), 27 G (best fit, thick solid line), and 45 G (too much depolarization, dotted line). The labels at the bottom of the lower panel indicate the position of the lines in the CN doublets with the corresponding N quantum number of the lower states. The labels at the top of the lower panel indicate the wavelength points which were chosen for the fitting procedure.

The assumed magnetic field strengths in the theoretical spectra are 0 G (no depolarization, dashed line), 25 G (best fit, thick solid line) and 45 G (too much depolarization, dotted line). Labels at the bottom of the lower panel indicate the N quantum numbers of the lower states and the line positions within each doublet (close to the bandhead N is omitted due to overlap). The labels at the top of the lower panel indicate the wavelength points which were selected for the fitting procedure.

The magnetic field strengths in the modeled spectra were set to 0 G (no depolarization, dashed line), 11 G (best fit, thick solid line), and 25 G (too much depolarization, dotted line). Labels at the bottom of the lower panel indicate the CN doublets with the N quantum numbers of the lower states. The labels at the top of the lower panel indicate the wavelength points chosen for the fitting procedure.
