Fig. 2
Histograms of the polarization amplitude of Stokes V/I in a continuum window. Top left: unfiltered data for speckle deconvolution (black), MOMFBD (red), and destretching (blue). Top right and bottom left: the same for application of a low-pass filter and of a weighted running mean, respectively. Bottom right: Fourier power vs. spectral frequency. Solid/dotted/dashed lines: unfiltered/low-pass filtered/running mean. The vertical black line corresponds to a wavelength of 10 pm.
