Fig. 2
Stokes images in a spectral window around the Ca i 4227 Å line. The observation was performed in the region shown in Fig. 1. Dark current and polarization calibration were taken into account, but not the instrumental cross talks between the Stokes parameters. In the Q/I and U/I images, the grey scale cuts are ±0.2%, while in the V/I image they are ±2.5%.
