a) Temporal evolution of Stokes V profile of pixel P iv located in patch A. b) Two-magnetic component SIR inversion of Stokes profiles at P iv at 19:58 UT. The wavelength scale is given in Δ λ from the Fe i 630.15 nm line rest wavelength position. Upper: Stokes I profile and the Stokes I profile retrieved from the inversion (red dashed line). Lower right: observed Stokes V profile (black solid line) and Stokes V profile from the best-fit inversion (red dashed line). The rest wavelengths for both Fe i 630.15 nm and Fe i 630.25 nm are indicated by vertical lines. Lower left: Stokes V profiles synthesized from the two individual magnetic atmospheres without taking their respective filling factors into account (green and blue lines). The atmospheric parameters from this inversion can be found in Table 1. c) Simple Gaussian fit to the observed Stokes V profile of a pixel close to P iv and also located in patch A. The slit scan containing this pixel was taken approximately 1 s earlier than the profile at P iv. The rest wavelengths for both Fe i 630.15 nm and Fe i 630.25 nm are indicated by vertical lines. Upper row: two anti-symmetric Stokes V profiles constructed with Gaussians and shifted with respect to each other. On the right the combination of the two synthetic anti-symmetric Stokes V profiles is shown as a red dashed line. Lower row: on the left side we show a synthetic negative polarity Stokes V profile (green line) and a reversed polarity Stoke V profile (blue). On the right side we show again the combination of the two synthetic anti-symmetric Stokes V profiles as a red dashed line.
