Abstract: We present a spectro-polarimetric study of magnetic structures supporting quiescent filaments, using the combined DLSP-Phase I and ASP observations. The observations were performed using the spectral lines Fe I 6301.5 Å and 6302.5 Å at the photospheric level, and Mg I 5172.7 Å and H I 6562.8 Å (Hα) at the chromospheric level. Using non-linear, force-free extrapolation models, we reconstruct the 3D magnetic loop-geometry and compare the viability of the magnetic filament dips as the true location of the filaments, as seen in Hα.
