Abstract
We analysed the vector magnetic field in a filament channel observed with THEMIS on October 16, 2004 in several lines simultaneously (Hα, Na D1 and Fe I). We performed the inversion of the Stokes parameters by using the PCA method. A high sensitivity was achieved in the polarimetric observations. Weak parasitic polarities were detected in the filament channel. We deprojected the observations into a local reference frame. The 180 degree ambiguity was resolved by using the chirality rules. The magnetic vectors indicate a concave topology (magnetic dips) in the filament channel.
