Zeeman-Doppler imaging sequences of solar quiet regions: magnetic and velocity measurements by the SOT/NFI onboard HINODE in FeI 5250 A line

This dataset contains two sequences of magnetograms, Dopplergrams and intensitygrams of the quiet sun near disk centre, which were derived from observations of the Narrow band Filter Imager (NFI) onboard the HINODE satellite (Solar Optical Telescope, SOT). The NFI provided filtergrams (40 mA FWHM) in FeI 5250.2 A spectral line (Landé factor 3.0) at 2 wavelengths from which Dopplershifts were deduced; the polarimeter provided the Stokes parameter V, a proxy of Line Of Sight (LOS) magnetic fields. The spatial pixel was 0.16” and the Field Of View (FOV) was a square of 112 arcsec². The two sequences provide the evolution during several hours of the magneto-hydrodynamics of the solar surface and can be used for further investigations.
