More than 1000 small isolated bright Ca+ structures (facular points) have been observed with the German VTT at the Observatorio del Teide, Tenerife. An analysis of Stokes V and Stokes I profiles of magnetically sensitive lines exhibit some typical properties of these features. The investigation is concentrated on those 40% of the observed structures for which the magnetic filling factor is larger than 10%
